The Guns of Degenham, Part 2

[Peter Laidler]

13 holes = L34 firing Mk2z for obvious reasons. Some of the other Q's asked have been answered on this forum very recently. But I'll answer them again later....

Added at request of someone that didn't understand. 2z= hot propellant with faster bullet. Need to slow the bullet down to sub sonic means venting off more propellant gas so extra ring of holes that JUST does it...... but only JUST!
