What is this WW2 item for? SF Co 6-42?

Found this in a junk box at a local flea market today. Anyone know what it is for?

Looks like the case for the Clinometer, Machine Gun.

Looks like a BAR tool case.

Looks like a BAR tool case to me, Here are two BAR combination tools, note the difference, there is also a third one that is different too. This tool would have been inside this case

I had one, it was a BAR tool kit

Yes! BAR tool kit. I am looking at mine right now....

OK I'll buy that, but it LOOKED like the Clinometer case. Except maybe mine had a rear belt loop...

Thanks for the info guys! I also picked up a real nice M1941 pack marked USMC Boyt 44 from the same seller. Its only the top part of the pack, but i am always happy to find any USMC marked gear. I will post some pics of it as well.

certainly not a clinometer case as it doesn't look anything like mine and I have the clinometer as well.

Lets see a pic John, I sold mine a bit back so it's not fresh in my mind...
