Vintage Recurve Bow ID Help - Specs Stamped into Riser

[SkookumDon]

IMG_2962[1][/attach]IMG_2963[1][/attach]Can anyone help me ID this bow? Someone thought it might be a 1960 American Amarco. Anyway, the specs are stamped into the riser. Not many companies did this, and I didn't think American did. Much thanks. IMG_2969[1][/attach]

I agree, could be a '60 Amarco ....
....with 2 corroborating details:
1. they did stamp their earlier bows e.g. the AO-68 lemonwood longbow
2. compare your tip overlay with that on said AO-68, white on black ....
