Winchester Trench Gun

[SemperFi1977m]

Im awaiting pics or a call to go see it in prson, but was wanting to ask around about these....

I found a local guy who has a Winchester Trench Gun with a manufacturing date of 1919. Here is the description: "gun is missing the original heat sheild- not much finish on it-has the U.S. and flaming bomb stamp-no rust or pitting-locks up tight and shoots well-end of the barrel is threaded -has slamfire action-mfg.1919-ser#683xxx with E on top. Serial numbers match"

I will hopefully have some pics to add to this, but what are these things bringing now days without a decent original finish, but having matching numbers and not beat to death? He is asking 400.

Thanks for any info.
