Welcome aboard southerncad, glad to have you join us. I did a forum search on Buehler and got a few hits. (We've had a few really good posts on them but it's been a while back.

I have what is supposed to be a 1959 Buehler Turbocraft that has a hull number of AO116. So, is this a '59 and is it the 116th produced and what does the AO stand for? Any input will be greatly appreciated, Thanx.
