Compliments & a Mk VII AVRE Besa question

Dear Ossie,

Once again you've posted a fine series of photos!
While looking at them, I also noted the AVRE Mk VII again & was wondering: did it still have the coaxial Besa MG?

Also, some AVREs Mk VII seem to have some sort of bore evacuator. Are those 7.2" gunned tanks, or is it a variation of the 6.5" gunned version?

Thanks in advance,

Erik Jan
