Gillette Fatboy?

[SirArthur]

I have just come upon a Gillette adjustable dated F1. It is 3.5 inches long and .50 inches across the handle. Is this a fatboy or are there any other characteristics besides the date and handle diameter? Thanks

Here's a Fatboy:

And here's a Slim:

Can you tell which it is?

Along with the difference in length notice the difference in the adjustment knob and the TTO knob at the tip of the handle.

I just noticed you said F1! It's a Fatboy. That's 1960. The Slims appeared in 1961.

Thanks for the comparison. You have been most helpful.
