Can anyone tell me if there should be a model number on the inside of the earstems on the pit boss 1? I'm unfamiliar with this model. I know to look for rivets instead of screws to spot fakes. Any other information is greatly appreciated!

Yes, there should be a model number.

Thanks Oak! These have the letter A in the hinge. Just dont have the model number and size in white. Everything else seems to check out. Probably err on the side of caution.
