I have 21 quick release pullers for sale, they are to fit 3/8" (10mm) cross shaft, 10 holes to fit 3/32" (2.5mm) pull rods. They were made for me by Bent Romnes of BenRom steels. I was going to use them on my guitar but due to a mistake I made I had to use round cross shafts. They are of course new complete with grub screws. I think everyone knows these things ain't cheap so if anyone is interested make me a descent offer and we'll see what happens. Cheers.
