Ok so today my mother stopped by with a present for me ....... I guess I've been a good boy. Well long story short she brought over and handed to me my great great grandfathers shaving razors...... straight, DE, and SE as well as my great grand mothers as well. Now I have been studying our WIKI and also online photo's to conform what I believe strongly to be a old type ball end ..... it has no double or single ring but absolutely has the correct head type and ball end and matches every picture of a old type ball end in every aspect. Now what has me excited is our wiki says that serial numbers beginning with the number 1 began in the middle of 1904...... I think I have that number 1........ here are some pictures you guys tell me if I am on the right track......There are no other numbers on this at all period.... at first I thought it was a letter "I" and maybe part of a military set from 1918 but the letter I was never used it stopped at "J" when WW1 ended. after we get this out of the way maybe someone can point me in a direction to date what I think is a 1920 SE GEM micromatic antenna. thanks for any input.
