A picture of the whole thing would help more.  It looks like a rebated rim in your picture.  If so, it is most likely for the Oerlikon gun used by the Navy in WWII.  Let me do a little more research, may take me little while.

Thank you for that wonderful information on 20mm AA guns...

Google was unable to find any information on a manufacturer  that uses "FSC", hence the question here.

Updated with a picture of the rim.

I can't make it out very well, but it appears to be marked on the side of the case as follows:

SPUN
NFM-L

A 20mm Oerlikon brass cased round made by the Florence Stove Company of Kankakee, IL.

Stand by for a link to a site with some info.

Does this case contain a projectile, and if so what are the markings on it?

If it is "SPDN," which it looks like to me (rather than "SPUN,") then it could be a reference to the powder used in U.S. 20mm rounds.

There's a reference to SPDN as a 20mm propellant charge here:  www.jmc.army.mil/DCG/Quality/propen3.doc


ETA:  I put in the wrong link.

That's interesting.

My Great-Grandfather was a USCG gunner on LST-509 during World War II. He is the one that gave me the shell shortly before passing away.

Where it gets interesting is that he was also from Kankakee, IL. Maybe he found the connect back then, and thats why he kept the shell.

I have nothing of value to add to this thread, but it's pretty interesting.

Top Shelf 2 20mm are 2/3 from right...1943 and 1945














Note the different rims on these rounds



IIRC: the Mk II is an AA round from deck gun and M21A1 is from aircraft cannon...I really don't know though

The interesting does not stop there, Sir, as one of my good friends, who turned 90 last October, was in the U.S.C.G. and served aboard LST-510 for the invasion of Normandy (though his "dinky little boat" didn't get near the beaches in the first wave, but rolled up with cargo nearly a day later,) and I had him at my house for dinner Monday before last.


ETA:  Just to clarify, I put "dinky little boat" in quotations because that is how Jack described it.  As far as you could tell by talking to him, he swung by the AO of Overlord to drop off a couple pallets some time after the invasion, and I only know what I do because I have seen his photos, and researched the hull number of the "dinky little boat" I've seen him pictured by.  As an aside, he joined up in December of '41, and spent a couple years on a wooden sub chaser doing convoy escort duties in the north Atlantic before 6-6-44.

I'll be doing my darndest to blow up that last one, and will show it to him Monday (he's coming over for dinner then, assuming he ain't too hung over after Jazz Fest*.)  I will let you know if he recognizes anyone ('cause it would be cool as all get out if he knew your GGF.)


*Yes, he will be overindulging in whiskey this weekend, as he does every Jazz Fest, as his little brother (88, and USN for WWII,) is in town for it.  Their big brother was also USN for that conflict, but he did not come home.
