Nope, no other marks other than what's shown & the identical marks are on the inside of the back & the dust cover so I don't believe anything is worn off.
I'd believe that the toadstool looking mark (& perhaps the I) below the case number is/are the maker mark but I admit the marks are a bit unusual & I can find any clue as to who the maker was.
Not really that important but I'm curious.
