In pic 1, I see a sportered foreend for M1917 rifle, a post-war Ithaca M37 butt, and what appears to be a Remington 11-48/Mohawk/Sportsman butt underneath that.

In pic 4 with the oil can, I believe I see a link for a browning Auto 5/Rem M11/Savage 720 variant.

In pic 5, I see an operating bar and foreend collar for an Ithaca M37.

Interested in selling the M37 butt? I might be interested in buying, if not cut down.
