What kind of tank is this?

[Althezenman]

Trying to find this tank. Anyone know what it is?

I know, I know, it's a gas tank!

Sorry, couldn't resist.

Possibly some sort of SL series tank from Honda early '70s dual purpose bikes? SL175 looks close if the gas cap is off to the right and not centered.
