Some of the carbines will have two serial numbers (identical numbers) on the top of the receiver

It was because of obstructed serial numbers. The s/n was on the heel, but the new sights could obscure the numbers. The 'flip sights' did not obscure anything, but the improved sights could. Inland was one of the makers that could have obstructed s/ns

So at the rebuild, the s/ns were stamped again (using a jig) if the s/n was obstructed by the sight, in front of the rear sight. My own '43 Inland carbine has this. One of the TMs outlines the process, I forget which

Mebanecop, is this what you meant about matching s/ns?
