My gas cylinder has a "punch" mark on the bayonet jug, is it true that WW2 gas cylinders have these? How can you tell if a gas cylinder is WW2 manufactered?

Thanks :lol:

Cylinders

All of the "narrow base" cylinders and the "saw cut" cylinders are WWII manufacture. The early Gas Trap cylinders are easily spotted.

IIRC the punchmark on the bottom of the Bayonet lug is something SA inspector's did. Both the narrow-base Gas-Cylinders and widebase Gas-Cylinders were produced during WWII. The narrowbase are easy to spot as the front-sight almost covers them from side to side, The widebase has more room for front-sight adjustment.

This is a wide base cylinder. Notice how the dovetail of the base protrudes out from the front sight. A narrow base will be flush with the sight sides.

Wide bases were being used by Sept 1943 so a great many WW2 rifles came with them.
