I've been a lurker for about two weeks now and have gotten a lot of knowledge from reading your threads. Wonderful stuff. Today I went in search of a razor and was lucky to purchase my first. It's a Gillette slim adjustable from 1966 according to your date chart. I paid $6.00 plus tax for it. I've yet to use it but look forward to it. This will be tomorrow, after I spend some time cleaning it. Everything looks to be in operational order. It is just really dirty.
I just wanted to say hello and thank you all for the wealth of information found here. It helped me know what to look for.
