how to date a fat handle tech?

so i recently purchased a very nice fat handled tech from one of our great members here.. i'm about to gift it to my brother in law and was just wondering what the best way to figure out the date range.. it doesn't have any date stamps.. so i'm just guessing it's pre 1951.. are there any other ways to narrow the dates?

thanks.

I once dated a fat call center tech.
But, that doesn't really help you much. ;)

Does it have letter codes?

Have a pic?

You can take a look here mr-razor History of Gillette Safety Razors there are some pictures of different era razors that may help with the general date range for you.

I'd just ask her out to dinner. Maybe she'll spring for it or you can go dutch treat. If she's real fat, you may want to go to a Krispy Kreme.

haha.. you guys are the best.. i'll definitely be going dutch with this one.
