I do like it when I find a radio with identifiable presets. It means we get to play a game I call Find That Radio. It also helps that this Zenith is gorgeous, though I think it's been refinished. This looks like someone stripped it and put on a thick coat of modern polyurethane. Looks good though, nice job. It's a model 5S319 made in 1939. [SOURCE] Zenith made a few Art Deco models mostly in the late 1930s and early 1940s: 5S126, 5S218, 7S323, 7SC33R, 6R631, 6S632 and the 5F233 which this one also resembles. The call signs on the 5 preset buttons are WJZ, WORK, WLW, WCAU and WGR. The WJZ-AM of today is on 1300 in Baltimore as it has been since 2008. But this is definitely the earlier WJZ. The original WJZ was out of Newark from 1921 - 1923 on 833 kHz. Based on the age of the radio, 1940s this is the WJZ in New York City that operated from 1923 - 1953 on 660 kHz. It's a 30-year window of time, but we can narrow that down I think.
1000 WORK-AM was a station in York, PA. They signed on March 17, 1932. After NARBA in 1941 they moved to 1350. They kept the calls until 1973 which narrows our time frame significantly on the bottom end. Despite using the call letters for over 40 years there is very little written about WORK. Most of what you will find focuses on Shorty Fincher and his Prairie Pals. This 1,000 watt station would have been mostly a local or regional station even in 1940.
Station WLW began as experimental station 8XAA around 1921. That start date is somewhat debated. More here. Putting that aside, WLW became WLW in March,1922 and operated on 833 kHz. It moved to 970 in 1923, then 710 where it stayed until 1927 when it made the move to 700 kHz where it remains today. This completely envelops the time frame and adds little to the story. Except for adding a pin to the map in Cincinnati, OH.
This WCAU is not the 98.1 WCAU-FM but the AM station which began broadcasting in 1922. It operated as WCAU from 1922–1990, almost 70 years. The frequency would have been 1170 when this radio was first plugged in. It was probably listened to before and after WCAU both the AM and FM sides were sold to The Philadelphia Record in 1946. After 1990 it became WOGL, then WGMP and is today WPTS, a news-talker on 1210.
The last station on the list is 550 WGR-AM in Buffalo, NY today. There is no debate on the frequency, they have been on 550 since 1928. It's interesting that the frequencies hop back and forth and aren't in any particular order on the presets. This 5,000 watt station would have been audible for hundreds of miles back in 1940, whereas WLW at 50,000 watts would have had it's frequency to itself across the whole east coast and been heard clear across the Mississippi river.Looking at the pins on a map I think the radio was East of Pittsburgh, PA but north of Baltimore, MD. There are just no local station in these presets except for WORK. If it was in a major city we might see local calls from those cities like WBAL or even WKBO if it was in Harrisburg. This really has to be in some reasonable distance from York, PA probably in a square between York, Hagerstown, Lancaster and Reading. Strangely I found this radio in Georgia.
