For those interested, here's a pic of my small US collection.

From left to right

1, 37mm AP M74 Projectile, M16 Case

2, 37mm HE M63 Projectile, M16 Case (I believe this round should be yellow!!??)

3, 57mm AP M70 Projectile, M23 Case

4, 57mm APCBC M86 Projectile, M23 Case

5, 75mm APC M72 Projectile, M18 Case

6, 75mm HE M48 Projectile, M18 Case

7, 75mm APC-T/HE M61 Projectile, M18 Case

8, 76mm APC-T/HE M62 Projectile, M26 Case

9, 3in APC Projectile, 3inch MkII case

10, 3in APC-T/HE M62 Projectile, 3inch MkII case

11, 90mm APC M77 Projectile, M19 Case

My project for the spring is to repaint these rounds to reflect original markings (obviously the 4 (1,3,5?,6) with original paint wont be touched)

I hope this is of interest to some.
