Thanks for the info! Now have more questions. I did not know what it was when bought it but it looks a good project.Being as there was no engine cradle it had to be one of the "keystone" framed Indians. The 1932 Scout Pony 31 cubic inch had a keystone frame with the engine as a stressed frame member. This bike was bored out to 45 cubic inches in 1933 and renamed the Motoplane. Then the 1934 Sport Scout used the same keystone frame design but more beefed up.
