3 inch, MK II shell casing.

Well-Known Member
I have this lacquered steel shell casing, 23 inches tall. What type of projectile will I need to keep it correct? The only markings legible is stamped in yellow on the case side. See picture. I suspect it is US Army, is it a tank round or an artillery round? Marking, " 3 IN. MK II M2 B1 Lot 3298 1944". I have it pictured next to a Navy 3 in for comparison. Once again, thank you for your time and knowledge.

For the M10 tank destroyer or M5 3" anti-tank gun. Made for killing tanks.

M42 HE or M79 AP or M62 APCBC would be appropriate. Or if you are really lucky an M93 HVAP.

I am confused by the 3 inch designation. Is the 3 inch also 76mm? In other words, so I do not make a buying mistake, what markings would the projectile be marked with?

You asked the same question on Feb 21. The answer is still the same:

About every 2 weeks to 2 months, someone asks the same questions.

Thank You for the search results. I have read them all, more than once to let it all sink in. My " searches " are terrible as I usually do not put in the correct nomenclature. Your results covered everything plus more. I noticed much talk about " restoration" processes. I will try to redeem myself offering a trick I have used on many older pieces where there is rust combined with original paint and it has become dull and faded. I use what is called Ospho, a mild phosphoric acid primer. I brush it on , let sit for 30 minutes, rinse with water and put in the sun to dry. The rust turns black and is hardened, and the paint that has oxidized becomes vibrant. I used it on an old, faded, rusty 155mm propellant tank, it now looks new issue. I also used it on the 3in MK II steel case, see pictures. The lacquered steel case came out wonderful, a nice " shine" where the lacquer was, and darkened, preserved look where the rust was. The yellow lettering now looks very bright also

Auto151MG,

Can you tell us what all the printing says on the outside of your projectile, because it is a navy 3 inch 50 cal projectile?
 
It's hard to read so here goes. " 3/50 AP PROJ MK 20-2 , below " BDF M66A2 (ARMY) ?R INTEGRAL". In white paint. Driving band is marked " LOT 108 42 MK. 29 MOD. 2 3in.A.P. sideways anchor US anchor DSB sideways anchor. Has a J and 3 stamped in the metal on the body. Has white paint markings above the other lines but is very hard to make out what it say's.
 
OK, that makes complete sense. The Navy APHE projectile used the Army fuze. The Army 76mm gun used the Navy 3 inch Illuminating projectile.

They kind of had a trade of technology going during the war.

OK, here is the bad news. That projectile doesn't go with that case. It goes in a 3 inch 50cal case, like the one shown at the beginning of this thread. The correct case has a more radiused and pronounced bottleneck.

The projectile you need is the 3 inch/76mm army M62 APHE projo. Its a little taller than yours with a bigger rotating band. If you look at the threads I listed above, you can find info on it.

I have one in another 3in/50 case. I picked up the one in the pictures at a gun show long ago and thought it did not look right. But for the price could not pass it up. It's one of two that I have seen with the red markings on. My projectile is a repaint from a gentleman I traded a British 25pr case and 37mm blunt tip training round for. I also got a 6pr APC British projectile. But he repainted that also.IMG_5869.jpgIMG_5870.jpg
