Err no, the first 35 flew in 1945 while the Mentor (Beech 45) flew in 1948.
Apologies, I got that ar$e about didn't I. I should have said they both shared the ruggedness of the undercarriage and airframe design concepts.
There was a straight tail aerobatic Bonanza/ Debonair also.
I bet the Mentor was fun to fly.
