My latest find: Cost $6 and looked terrible but has cleaned up fantastic! C/w 5 blue blades and 2silver blades. Wt=47g I have seen these sets before (there are two in that auction site) but i can't find the exact one on @mr-razor site. It seems to be an early Tech #77 set? (I say early because the diamond baseplates seem to be earlier than the flat bottoms). Either way, it is quite a thing and i doubt it has had much use. I wonder if those blue blades are original? The silver blades are I4 1963.
