Here is a vintage Convair USAF T-29 Aircraft Navigation Trainer Chrome Ashtray Desk Model. This display model/ashtray was manufactured by Allyn Sales Co., out of Los Angeles, California. The port side propeller has a broken, and missing blade. There is also much pitting to the chrome. The good news is that the oftern broken and or missing black glass ashtray is still in place, with no cracks, breaks or chips. The airplane itself measures 6-9/16" long, with a wingspan of close to 7-7/8" wide.
