Jim I didn't realize at the time but the receiver was cast pot metal with a sheet metal cover. Lived and learned since then. After about 8 years the barrel could visibility move up and down. With the last shot the barrel fell out, the receiver cover flew off and the top of the block that held the barrel went flying in multiple directions. Back in the late 70's I paid $86 plus tax for it. I sold all the parts except the receiver individually on gunbroker roughly 20 years afterward and netted $486, the 32 rounders brought the most money. Who knew these things had such a following.
