A bunch of between the Wars and WWII Colt barrel markings

[cfc]

From 1924 Transition K to 7 marked. Missing G7, N, D and B barrels.



Springfield Armory (S P) barrels with Heat Lot numbers and w/o, and partially stamped "cross cannon" on the right lug for one w/o heat lot.

Don't forget the Springfield barrel with the drawing number.

A very impressive assembly of barrels. Thank You.

D and S barrel. D is [C] marked on the right side of lug. S is COLT .45 AUTO marked.

Very helpful thread.

The D barrel looks like a B missing the top loop, or low case b.

The D barrel looks like a B missing the top loop, or low case b.

Do you have a B barrel to compare it to?

[Johnny P]

Naw, still looking for one....

Didn't think so....

Nice grouping of bbls. Johnny, that Springfield is really different, and the D is great D :-). Thanks for sharing.
