British M20 Bazooka practice rocket 3.5 inch markings

[BMG50]

Nice addition to a 3.5 rocket collection, the end result. I believe it could penetrate 10inches of armour.
Here is another photo of the HE sub head, as you can see The HE lettering, a TX below and the a XT and UK and the letter M. Above looks to be the start of practice PR. There was the black ink mark with arrow in the middle around the back but its gone now.

I can't recall ever seeing one. But both the Pam (9, of 1953) and JSP 316, corrected to 1988, show the practice round with HE SUB stencilled beneath the designation markings, so clearly it was fairly common. BMG50 might want to note that the letter height is shown as larger than the designation letters in the Pam but is the same height as the designation letters in the illustration in the JSP. So it is quite likely that variations exist. Life is never easy.
As a parting shot, pun absolutely intended, here is a pic of the copper slug that was supposed to insert itself into the tank hull after the HEAT charge had done its work - I am very carefully phrasing this, Barney please note, - and to whiz around, thus ruining the day of all human occupants.
I picked this up myself after a live firing practice (it was VERY hot).
