While shopping around the flea market in Front Royal my youngest son saw a few razors in a box and called me over. I bought all three for $6. One was a modern Merkur that had been twisted together so tight I broke it trying to get it open. The other two are pictured above after a little cleaning. Both are Gillettes with no date code. I think one is a heavy Tech from just before 1950. It's in good shape but nearly all the gold plating is gone from the blade cover. The copper underneath does polish up nicely however. The other is an old style Super Speed. I think it dates from the same time. The only brassing is on the TTO knob. It had a "Safe-T-Guard" blade in it. I think those are from the late sixties so I guess this razor was used for about twenty years then laid around for another forty. Am I correct in the identification of these?
