Wow, I guessed wrong on the vintage. I was thinking it looked like a "59er" sort of design.
Given it must have been after '68 (great bit of info about the AMO
fact), there's a 70 in the serial number - may be the year.
The bow is very, very simple - not even a groove (vertical) in the limb, very plain riser, etc. Extremely light in the hand.
Knew it wasn't anything special, I just want to know a little about it, since it's all I'm shooting right now. My Javaman Falcon is waiting patiently 'till my shoulder heals.
Thanks again, all. What a wealth of help, and knowledge - as always.
