What is a Stewart-Warner 1451 Worth Today?

Collector Value of This Vintage Radio

The Stewart-Warner model 1451 using the R-145 chassis is a fairly scarce 1937 tombstone radio. The collector value of the 1937 Stewart-Warner Model 1451 is shaped by a combination of factors that extend far beyond simple age. While Stewart-Warner radios generally do not command the same premium prices as comparable Zenith shutter-dials or certain high-end Philco consoles, the 1451 occupies an increasingly respected niche among collectors because of its rarity, dual Canadian/U.S. production history, attractive late-Depression styling, and solid technical design.

Documented Sales & Comparable Evidence

This radio is a rare, hard to find model, Radio Attic has sold 19,535 radios since 2005 - 639 in the last year alone. Yet, they have not sold one Stewart-Warner 1451.  This is currently one Stewart-Warner model 1451 advertised on eBay for $683 CDN plus $315.98 for shipping. This example is not restored and is untested — its a project radio (something you buy to restore and resell). It is also missing the stainless steel bands on the cabinet.

As rare as the plain1451 is, the deluxe trim variation with the stainless steel bands are rarely seen at public auction.

Current Market Value

Based on current asking prices and comparable Stewart-Warner sales in the vintage radio market:

Comparable restored Stewart-Warner sets from the same era regularly appear in the several-hundred-dollar range, with especially attractive Art Deco models with deluxe trim well exceeding $1,000 when restoration quality is exceptional.

Why the 1451 Has Become More Desirable

1. Canadian Production Adds Scarcity

The Belleville-built Canadian versions are significantly less common than American Stewart-Warner sets.

Collectors increasingly value:

o  Canadian branch-plant radios
o  alternate chassis designs
o  region-specific engineering differences

The fact that the Canadian 1451 uses a substantially different detector/audio topology than the U.S. model makes it more interesting than a typical export variation.

For advanced collectors, this transforms the radio from “another 1930s tabletop” into a historically distinct production variant particularly models with the stainless steel trim.

2. Shortwave Capability Matters

Many inexpensive 1930s tabletop radios were broadcast-band-only sets.

The 1451’s inclusion of: broadcast band, two shortwave bands and multi-band tuning adds meaningful collector appeal.

Shortwave-capable sets are generally more desirable because they:

o  represent higher-tier engineering
o  offer greater operational interest
o  connect directly to the international broadcasting culture of the late 1930s

3. Cabinet Styling Is Strong

The Stewart-Warner 1451 benefits from:

o  balanced proportions
o  Art Deco influence
o  attractive grille geometry
o  warm walnut veneers
o  visually pleasing dial placement

Collectors strongly prefer radios that display well in a room, and the 1451 has a refined, understated elegance that photographs beautifully and presents well in collections.

4. Restoration Quality Changes Everything

In today’s market, restoration quality has become one of the single largest value multipliers.

A professional restoration with:

o  properly rebuilt chassis
o  accurate toner lacquer work
o  grain filling
o  correct cloth
o  proper dial preservation
o  aligned RF/IF stages
o  safe power supply rebuilding

can increase value dramatically.                

This is especially true because many surviving Stewart-Warner sets were historically considered “mid-tier radios” and therefore did not always receive museum-grade restoration treatment.

As a result, truly exceptional restorations stand out immediately.

Canadian Radios and Emerging Collector Interest

Over the last decade, collector interest in Canadian-produced radios has steadily increased. Many collectors now actively seek these out because these radios represent a parallel but distinct branch of North American radio history.  The Belleville-built 1451 fits squarely into this growing niche.

Insurance vs. Market Value

One important distinction for collectors is the difference between:

>>> market value

>>> replacement value

>>> insurance value

A typical private-sale price may be:

➡️ $500–$900 CAD

But the replacement cost for a similarly restored example could easily exceed:

➡️ $1,500–$2,000 CAD

because reproducing a museum-quality restoration today requires:

1. hundreds of labor hours
2. scarce components
3. specialized finishing expertise
4. cabinet craftsmanship

Where the Highest Values Occur

The strongest prices today are generally achieved through:

1. specialty radio auctions
2. high-end collector sales
3. curated antique electronics dealers
4. museum-quality online listings

Exceptional photography and historical documentation now play a major role in final sale price.

Collectors increasingly pay premiums for:

1. storytelling
2. authenticity
3. restoration transparency
4. historical presentation

This Example: Serial 11493

A Belleville-built Stewart-Warner 1451 with serial number 11493 occupies a particularly interesting place in the market because it represents:

>>> confirmed Canadian production

>>> the primary 1937 manufacturing period

>>> a less common chassis variation

>>> a transitional era in North American radio design

Fully restored to a high standard with excellent cabinetry and documented workmanship, such a set could realistically occupy the upper portion of current Stewart-Warner market values.

Final Summary

The Stewart-Warner 1451 is no longer viewed merely as a “mid-level old radio” especially sets with the deluxe trim.

Today these are increasingly appreciated as:

o  a historically important Depression-era receiver

o  an example of cross-border manufacturing adaptation

o  a technically interesting dual-version design

o  and a visually attractive Art Deco collectible.

Final Assessment

Based on the review of photos and watching two videos provided by the restorer I find this to be an above average restoration.  The cabinet has been professional refinished and the quality reflects the many hours that went into making it near flawless.The sound is good and is what you would expect from a detailed electrical restoration.  Its serial number indicates that it was manufactured in Canada which adds to its value as a collectable radio. For collectors who appreciate Canadian radio history and high-quality restoration work, this Belleville-built 1451 radio with the deluxe stainless-steel trim represents a particularly compelling and increasingly scarce survivor of the golden age of radio

On the downside the reproduced stainless-steel trim is not perfect. Although it looks flawless from a short distance, a close up inspection reveals lamination in the bands. This could be a concern of the antique purest but unlikely to be an issue for most collectors.

The addition of the FM module adds real value to the non-purest and allows this 89 year-old radio return to its former life as a daily user. This clearly adds value to the non-purist collector which is reflected in the appraisal.

Given its current condition and in consideration of the above mentioned flaws this1451 with the Deluxe Stainless Steel trim should command between $800 and $1,000 CDN in today's market.
