I just got my 1973 Black Beauty today. I gave it a good scrub and it looks 10 times better than the pics on eBay. Can't wait to use it. All the numbers on the dial are still black too!
I shaved with it today on 3. At first I thought "man I've got techs that are more aggressive". After a 3 pass shave I ended up getting the most gentle and smoothest BBS I've ever had. Next shave I'm gonna crank it up to a 5.
