When Epiphone introduced their Masterbilt archtop guitars in 1931, the Olympic was the least expensive instrument. It was offered in Concert size with a 13 5/8 inch body and priced $ 30. The 1932 catalog states: catalog 1932
Wiedler wrote us July 2015: “The Olympic was in the first catalog as “Concert” size (like Zenith). The info that it was only 13” wide in 1931, and widened to 13 5/8” by c.1933, was already in Gruhn’s Guide 1991 and repeated all over since. However, all pre-1935 examples I know actually seem to be 13 5/8” wide like the early Zenith, also the earliest in the registry – SN 5752. I never heard of a smaller Olympic. The same goes for the Beverly model (earliest SN 5478).” See also : Olympic s/n 6851 and Olympic s/n 5454
According to Wiedler Epiphone produced from 1932-’44 around 4100 Olympics of which now 290 examples have been registered.
