Hi Ted;
Your picture with the concours trophy is in Wynn Paul's column in the November Nats issue of Model Aviation. American Aircraft Modeler went out of production in early 1975 and was replaced with AMA menbership later that year with Model Aviation as we know it now. I check the SIG adds all through 1978 in both Model Aviation and Flying Models and didn't see the phot that you refer to. Some young punk kids named Fitzgerald seems to have hogged a lot of press space at that time with his Chipmunk. Must have edged you out!!! But seriously folks, if we can nail down the date of the add, I'm sure I'll have it. I haven't checked Model Airplane News yet, and they still had C/L coverage at that time and the SIG add was different in the other two mags, and may have been in M.A.N. I have tools scattered all over my garage from a motocycle project I'm working on, (1977 Penton 400 MC-5 that I'm converting to a GS model) and tonight or tomorrow I'll look some more. You do have access to Model Aviation through the AMA website in the Members Only section. They have scans of M.A. from the first issue up through 2000, I believe and may have updated more recent issues. If we can figure out the exact issue, I'll get it for you Ted.
Type at you later,
