At one of the Tulsa shows I bought a new replica butt plate for 16 ga M 37. A couple of aisles farther and there was a lady that had a plastic box full of butt plates and I bought 3 or 4 for Ithaca M37 from her. I got home with 4 or 5 butt plates, and only one of them fit right.
I just went to look and I have 3 of them left, including the new replica. One of them is 4.730" X 1.470", the other two are 4.830" X 1.465". If you think one of them will work send me a PM or email either; hdhawgr@centurytel.net
