Jase, SHG Model supplies list 2mm shafts and brass props..I have not trawled thro to see if there are any 4 blade jobs, but a brass 3 blader may look ok in the interim. OTHERWISE i might suggest calling the prop-shop… http://www.prop-shop.co.uk. as they do a good range of non-standard sorts of things, and should be able to thread some correct size props in 2mm for you ??.
