I have a Model 60 in the original box. I don't know if it has been fired. I have not fired it and I got it in the '70s.
All of the original papers are in the box; registration form, the sheet with parts list, maintance, specs,etc., brochure on knives and a brochure on ammunition.
The end of the box reads;
Model No. 60-
Fin 55
Barrel 2
Stock R
Pkr 5
Special Feature 1762
Ser No. R159917

I would like to know the value.
Thanks,
Jim

Probably around $350-$400. They are not rare.
