Is it possible to decipher where a case and projectile were made by the codes stamped on them?  I have two WWII new, empty 75mm cases and one 37mm empty case and empty projectile.  I would like to determine where the cases and projectile were made. 

 

By what little I could find elsewhere, the projectile is supposed to be an AP unit, that is if the info was correct.

 

Thank you in advance for any and all help.

Without pictures, no. Here goes the basics- head cases were metal stamped , eg, 75mm , M18 , BB, 1942 at the plant. That would signify a 1942 M18 75mm case made by company " BB". WHEN it was loaded at the factory, with either AP, HE, etc,...it was INK stamped on the head case over the factory metal engraved basic case info, with the powder lot number,completed projectile type. Same with a projectile. The loaded projectile was yellow INK or laquer marked ( HE) with type ( M62A1, explosive filler type ( TNT, Comp B etc,) , ( G) gun or ( H) howitzer type ( 75MM G- 75mm gun, tank----75MM H, 75mm howitzer)...that is the basics, and that is why original ink marked complete rounds are rarer and very desirable by collectors. I have a few original examples but this site will not load my pictures. Basically, The black ink markings on the case head and yellow HE ( or white ink markings - inert or AP) on the projectile were applied WHEN loaded at the factory. You will not see many as bubba likes a shiny case and polishes off the ink marking from the used case or the case was never loaded. Same with the projectile but finding an original yellow ink marked HE projo is rare as it obviously was downloaded at one time...you can find original AP ink marked projos as they were usually just large metal slugs...last word, beware, many collectors " re- ink" projos as they look nicer in original, issued colors. Make sense? Lastly, I stated general facts, there are differences and variations (as in the rarer US 3" G rounds with steel cases).

A few examples that I could get loaded. This one from a US 3" G, inert loaded, if loaded, the ink would have loaded up information and lot numbers, etc.

Another, a well marked 75MM H M5 casing, loaded up with an M48 HE projectile. My projectile pic ( a 1944 dated M48 HE) will not load ( to large) but you should get the concept. There is much to ordnance collecting, WW1 pieces to modern day differ in markings but the concept has been unchanged.

Also, for historical info, I have seen common 105H WW2 dated brass cases ink marked ( when loaded or assembled) with early Vietnam era dates ( 1960's). We made a bunch of them in WW2, obviously surplus enough to last way past the Korean War.

Thank you for the reply. 

 

My two 75 mm cases I will have to look at tomorrow.  However, none of my cases show any ink or trace thereof on the bottom.  Only stamping in the brass base, and in the case of the 37mm, stamping on the projectile rotating band.  My wife has the camera and is not home at the time, so I will give you the info off of my 37mm case and will supply pics of all tomorrow.

 

On the 37mm case bottom.  37MM M16  LOT 7 12-50  flaming bomb?  G.L. 1941

 

On the projectile rotating band.  lot 22643 -26- 1942  SG  37MM M51B1

75 mm shell casings.  In the event that the pictures aren't clear, the info on the bottom of the two shells is identical, except for the lot number.

75MM G

Not sure who the manufacturer was for the 37mm. The 75mm is Scovill, CT. It is pre-WW2, WW1 possibly. The WW2 case had an M18 designation.

Thank you.  Can you tell me what the insignia is at the bottom of the last pic on the 75mm shell base?  Flaming bomb?  Also, could you please tell me the insignia on the 37mm shell between "50" and "G.L."?

Correct. Time period for that Ordnance stamp- up to the end of WW2....maybe a year or two earlier. I have original ordnance crates ( and cartridge ammo crates), they all have the crossed cannons, my crates post WW2 have none. I am not sure exactly when that stamp was discontinued, my 1941-44 75mm Sherman tank rounds do not have it, but my 1943/44 dated 3" gun steel case rounds do have it. Maybe someone can add some info.

Crossed cannon ordnance mark is between the 50 and GL. Impressed sloppy, but there.All three pieces very nice, and correct...now the hard part, keep your eyes open for WW1 era 75mm projectiles...getting harder to find- $200 plus for a good one with an unfired driving band. A pristine " BSC" one just went for $275 plus shipping and 20 percent commision, ( Bethlehem Steel Corp marked).Original colored ones ( red) go for way more than mentioned.

Where would be the best places to shop for such projectiles?

If one slips through ebay, they do, but you will pay as they usually have multiple bidders", Gunbroker, same but you will not get clipped as bad as eBay, best local maw and paw antique shops many were made into lamps and you can find a fuze which is usually not there. Or put a want to buy on the many militaria boards out there. All that said, with the increasing demand for Ordnance, if I was in your spot with very nice cases, if I found one , does it matter if you "overpay" to fill such a nice case? " overpaying" today matters little five ten years down the road when they become " unobtainable". In just the past 5-7 years I have seen yesterday's doorstops appreciate immensely. Jeeps, patches, ammo,medals, uniforms, helmets, bayonets- nothing has outperformed quality Ordnance...very little out there to be found. That said, I will keep my eyes open for one as WW1 is not my area of interest.

917601,

 

Thank you very much for the information and your help.  The cases were in a house my parents bought in the very early sixties. The previous owner had worked at the local loading plants in WWI and WWII.   I guess he brought home some samples. 

 

He was an engraver by trade in Germany when he came here as a young man just before WWI.  That accounts for the engraving on the two cases.  Surely not his finest work.  The work this man could do was nothing short of amazing. Steel grey eyes that looked right thru you, strong as an oxe and only 5'4" tall and the most friendly person you could ever meet.  

 

Thank you again.

 

 

 

So I am ahead of the game, as the cases cost me nothing.  I would never get rid of them, as they are of incalculable sentimental value.

 

Thank you again for your help.

Is the M5 or M18 better? What would each be worth?
