And it still won't be a 52 B. Find what you want and buy it.
My exact thought... I was going to comment lastnight, but thought it might be rude. Just leave the 69A alone. Sell it to someone that will appreciate it!! Find a 52B and be happy. They are around. I found one last year and it was no where near what they were wanting for them 5 years ago. The time to buy is right now.....
Good luck with your search. They are out there, and speaking of really nice 75 target rifles, I ran across one a few months ago at a small gunshow and the guy wanted $400.00 for it. I should have bought it and no I am not giving out his contact info... Don't even pm me..
