Anyone know were to find the large eye sling swivel studs? The ones used with the sling hooks or thong type slings. A lot of the vintage rifles have them. My Win. Model 54 has them and they are exactly like the Rigbys I’ve seen. I could just rob the rear swivel off my 54 as I will have a barrel band on the front, but I’d rather find a new set if possible. I can’t post a picture but I’m sure everyone knows what I’m talking about. Any help appreciated
