Antique store finds. Help Needed identifying years

[DTJ12777]

Hello all

I'm still new to vintage razors but I went to a local antique store and scored 5 safety razors! I think I've been able to identify the models but I am not sure on the years was wondering if anyone had some information or history about these razors

I'm thinking I have as follows
Gillette milord
Gillette rocket (seems to be 40s style)
Gillette tech (marked L1)
Gillette 1959 fatboy (this is the only one I know for sure the date)
Valet auto strop
