[Mauser720]

Hello Pablo -

Yes, if the serial number is 1143 then the number on the rear toggle should be 43 too.

Since you have the number 50 this is a mismatch and it does affect the value to a collector. So to a collector, that is probably about a 50% reduction in value.

It makes the gun more of a "shooter" than a "collector" even though it is still an interesting gun.

Thank you for sharing.
