Interesting Question.....Mine bears an 11-43 Underwood barrel with a small P proof.

[Bruce McAskill]

Not all NPM barrels had the punch mark proof.

Do you rhink that will sell for $3600?

[jimb16]

It might. They are quite rare.

Why stamp SN twice if you can read it?

[wtmr]

it was a CMP auction gun, it sold twice

[painter777]

Marcus,
I forgot this is the one you won on the CMP auction..and returned because the double struck serial number wasn't in the auction's description.

[wtmr]

yeah, it sold for more the second time from memory, at least one of guns I returned did. By like $500.
