Case and Bezel 10K Gold Filled, Measures 43.30mm lug to lug and 25.10mm not including the crown.
And now I've found what I think is another 1938 Montgomery ad from main database. Click for full (blurry) ad.
There appears to be a sears ad for the Oxford (or similar catalog) w/ two different dates based on the graphic file name. One for 1938 and another for 1939. Appears to be the same ad placed in various threads, so I'm looking for the ad in the main database to determine which of the two is correct. Didn't see any Oxford ad in the main database for 1938, but I could have missed it.
Out of time for today.....

Yes Dennis. I've thought case measurements should be requested for every entry. They are often so helpful. If there were a field for case measurements, like there is for jewels, movement model, etc.... it may help remind folks how helpful this info can be in the ID.
