Size 4 or 5 bodies weighing between 9/32 and 3/8 in brass work. Torpedo or snowman or whatever. Then just plain brass size 4 or 5 blades, hopefully in .032 thickness. I can oxidize (definitely) or silver plate my own (hopefully, need to test my contraption out).
If I can't get anyone to go in on an order with I'll just bite the bullet and get 125 of each from Fisherman's Shack.
