My sister found this at a yard sale and picked them up for me. They obviously need some cleaning, and that step has already started. I have ordered some Gem SE blades, and they are on the way. I've never used a Gem-style razor, so this is all new to me. I'm not 100% certain what models they are, but I'm researching.
Wish me luck, nd if there are any pertinent details I should be aware of feel free to share them here.
