My uncle passed away a couple years ago. He gave me a rusty old Kmart 4-10 model 151 it would have 0 value except sentimental for me. I would shoot it if i get it back together. The forarm/ forend assembly is missing. I would buy a complete shotgun for the forend if needed. They have no collectable value that i see. I have some pocket knives and old wooden fishing lures i can trade also. Ive been watching ebay for awhile, nothing there yet. I did send some emails to parts dealers but got no reply. So I keep searching. Thanks
