Old Gillette identification

[SBBO]

Hello,
I've just bought these 3 razors on ebay.
Can you help me to identify the models ?
Thank you very much

Seb

From left to right using right hand photo, 1930's NEW, fat handle Tech and ball tip Tech. The Techs may be able to be dated by checking for a letter and a number on the underside of the head. The fat handle may not have one which would place it in the 1940's. See the Gillette three piece thread in my sig for more info.

It looks like the NEW has the wrong (fat handle Tech) handle
