what is it?

I recently bought a 98 receiver that would be a good donor for conversion to the flat magazine. It'd be nice to find one of the pictured kits. I had the receiver a couple months before I noticed that the front magazine hinge pin hole was gone, and the rear one partially gone! Can't imagine anyone liking that dogleg Enfield bend, but maybe it once belonged to someone who served with an Enfield.
