This is my set of Broaches out of a junk box at a Pawn Shop, the box was rusty and when the fellow walked up I said .25 cents he said yes gave him a dollar and walked out, they are a Treadwell brand sure they are quite old but work great, there is no shoulder on the top of the bushing like some I have seen on the tube, 1/2 to 1 1/2" with three keys, I broached a five inch 1/4" key last night, works great, I had about given up on Pawn Shops lately, but renewed interest again, Lathe Nut
