I just got this Saturday and did some swapping for it .I did some background work and looking through some old catalogs here I do believe it’s a 1964 year but could be off a year not sure? Anyone who can shed a little more light on it please join in and let me know if you don’t mind . In the meantime here is a few before and after pictures I took of cleaning it up.
I made a 14 strand B-50 Dacron and puffs for it and this old girl can shoot pretty good.
