BSA, Unless you just have to have an org. 52C sporter, bide your time till a 52R Zanders HB sporter pops up, they are super well made, shoot like a house afire and hold value to the max, there is a lot of debate as to how many Zanders had done but the best I can tell is 250 satin and 250 gloss. I bought mine several years ago and could not be happier, it shoots right there with my 56' 52C sporter at about 1/4 the investment! The 'Rs' had a lawyer pin installed to limit wt of pull but it is a simple small roll pin to remove, then you can safely reduce wt of pull to about 2 lbs with no creep. Next Time I get the camera out I will take a pix, I may have one on photobucket. very best WinPoor
