I don't know what the extra markings are, but are you sure that's a pressure test cartridge? That headstamp is the same that was on the .50 High Velocity Experimental Case made by Bridgeport Brass Co. That's what the "B" in the diamond signify. Isn't it actually a 20mm case necked down?
Could the extra markings indicate the type of bullet that was being tested?

Hello Ray, Attaching a picture of the cartridge and projectile. The projectile has a coiled wire 'roatating band', wrapped around five times. I believe it is for barrel erosion testing.
The "B" in the headstamp appears to have been applied by a hand punch....so am presuming it was part of a small volume test batch(?)
Yes, these cases were derived from 20mm cases and initially they were produced from necked down cases, however the BBC production were purpose produced.
