Info on vintage razors?

I love my red tip and am having it shipped off to delta echo for a replate.

If you are a seasoned de shaver, slap a feather in that bluetip. You will have a smooth stubble free result. A feather in the ball tech might be a tad aggresive for a feather.

Thanks for all of the insight everyone. I scrubbed them with soap and water last night and am going to use one today. They are definitely going to be heirloom pieces as everyone mentioned. I am very honored to have them. The letter/number combinations are as follows:
Tech-L1
SS-y3
Blue tip-d4

Any pics after you cleaned them? Would love to see how they turned out.
