Brass Collectors

Hey guys, I've been collecting brass for a short time. Mainly for my son to help teach him about the different firearms.

Question, I have a 40mm shell from 3-1945. The markings are 40MM MK.2 MOD I, then an anchor symbol and HDH and SMC LOT 210, it's 9-7/8" long with a slight taper.
Is this a foreign shell? It is tarnished and I was thinking about polishing it but can/will that ruin the value? Does it have any significant value to begin with?

Any info is appreciated, Thanks!!

    No, it's a US Navy antiaircraft round. It's the big four gun mount that you see on battleship footage firing at aircraft. The crew drops clips of five rounds into the feedtrough. However yours has been cut down to salute battery size at nine inches. Not real valuable, but neat as they are made out of steel now.

    Thanks P3, it must have been cut on a lathe? ect some time ago, cause I can't see any saw marks and it is evenly tarnished..

    I've seen these used on WWII movies/documentarys and figured it to be an anti-aircraft shell, but wasn't sure.

    Hi,

    The shell is a 40mm Bofors round made for the US Navy.

    Skyking is correct and the 40mm Bofors anti-aircraft guns were used on everything from destroyers to aircraft carriers. These are the guns that were sometimes referred to as pom-pom guns because of the sound they made.

    Regards,

    Sounds good, do you guys know the origional lenght of the 40mm shell?
    It currently measures 40.4mm, so it couldn't of been cut too much.
    I googled it and couldn't find much.

    The proper name for the 40mm Bofors L/60 AA gun cartridge is "40 x 311 R", my sample measures 12 3/16 long.
