M468, 105-mm, tpt

Quick question for the LOT CODE buffs ...

So we have NOR ... which I am assuming to be Norris (which we see on the projectile).
The MA on the Cartridge I have as Milan Army Ammo Plant. Did Milan make the case and then Norris accept them (putting their stamp on them), or am I missing something with the MA on the LOT CODE on the base of the cartridge?

No Joe, Norris made the case and projectile. The octagon acceptance stamp was used by the inspectors in the Norris factory.

K. T. Norris perfected the method of making steel cartridge cases in WWII. He made his millions doing that, and then started making projectiles.

The big trade secret was how much metal could be moved in each ironing operation.

Do you know why the Army would have marked them with the MA then? I am trying to learn about LOT CODES. Things like when and why certain things were stamped when they were. I know in this business nothing is certain, but the more I am learning the more confused I get at times.

Joe, I have no idea about lot codes. Mike Weber might know. He has done a lot of consulting

Yes Milan did the assembly of the projo to the case. Not sure who loaded the projo but am assuming it was Milan also, most Ordnance plants did both for the same round a TP and a service round
 
ahh ... makes sense ...

So Norris made the items, Milan then put them together. OK ...

Thanks Mike.
 
only thing I can not confirm is who loaded the inert material, but like I said I assume Milan did it
