Parker Reproduction box label
 

Misspellings or counterfeit?

If this were a Rolex, obvious errors such as this, would tell you it's a fake. There are known counterfeited Parker Bro's guns, could it now be the Repro's turn?

The boxes for my three Parkers all say "Pistol Grid", too.

How'd they do with "GUAGE"?

I only have two original boxes for my Repros. Both are differently labeled, but they at least are spelled correctly.

I found this listing on GI. are you suggesting the gun itself is a knockoff of a repro or that the box was knocked off to embellish the value of an original gun? If that gun is a knock off, they could re-open the repro business outright.
