I am looking for your help. I picked up a series 34 Toyo Kogyo yesterday. I lucked out and it is an all-matching gun with a complete mum. The extra bonus may be the sling. It has an M1 carbine sling attached that has obviously been on the rifle for a very long time. I am hoping it is an original so I can restore it and swap out the reproduction sling on my Standard Products rifle. Thanks!
