Hello, she's definitely beautiful! Check out libertytreecollectors.com; they've got a sling section and I think they still have some specifically for 24/47's. Otherwise, pretty much any Yugoicon M24 or even a VZ24 sling would be close enough. They are all very similar, the M48 is the only one that's different and it's closer to a k98k sling.

A great find there man, I used to have one then traded it for something; I've been debating getting another one....
