Earlier when I looked, I thought I saw a model number of 207 on my version of this radio (4" round speaker); however, looking more closely, I see what is says is "RMA Code 207" on a sticker that on the chassis. The sticker also has a Serial Number of B56923. There is no other indication of model number on the radio, unlike the one pictured that has a model number on a sticker directly above the hole in the back cover through which the power cord emerges.
