Identify Anti Aircraft shell etc
I picked up what appears to be a 1" AA shell at the weekend. I believe it's 1940 date, would like to find out if I am correct in thinking it's AA and what gun it would be fired from. It has a solid boat tail ogive, much like a rifle bullet. Primer appears unstruck.
I have placed a .303 case and 75mm French case for comparison.
Also this particular 75mm case appears blown out around the central section. Could it be from being fired in a well worn breech? It does not appear to have been hammered. It is of 1918 vintage.

Looks like about a 20mm size. What does the bullet measure, or the case mouth?

The bullet measures exactly 1 " at it's widest. Measured with a vernier caliper.

I'm guessing it is a 20mm oerlikon round.

The round's diameter is 1 inch, which is 25,4mm. I am assuming the 40 stamp on the base is the year of manufacture, but it's a guess.
I've not found anything on line yet with similar dimension's; so will try and expand my search.

2 possibles for the 25.4mm Rimmed ~ LM - Cartoucherie du Mans, Le Mans, France, CN - Unknown Factory, France
As for the 75mm French QF case the impact dent on the case would make it appear to be a bulged case as you can see the side walls as the pic depicts taper back in towards the just visible shoulder & case neck, I feel the case is only deformed from that damage sustained by unknown causes.

I have a Japanese 25mm round that looks just like it with the exception that my case is rim less. Plus it has Japanese script on the base.
