You can keep the can of goo, but I wouldn’t mind paying just shy of a dollar for a 1953 GEM with ten blades.
Adjusted for inflation, 98 cents would equal a little under ten dollars today. Not a bad deal all told – it’s about what you would have to pay for a modern multi-blade cartridge handle with a couple of cartridges today. Ten GEM blades should last longer than two modern carts though…
