A fella gave me these a few months ago. I do not know, for sure, which riser it is. I found "A-1502" marked on the side near the lower latch. The limbs are warped. they look OK until you try to string it. I can't even keep the string on it because it twist so badly.
Sweet! You have an A riser and #1 limbs. Those limbs make a 56" bow at 43#. The wood A riser was only made from 1969-1972 so you have a very nice collectable
