Hi Infidel, has it got an original Serial number? I may be able to pin a month of production down for you.

Don't worry about the bipod, its a Brit Daimler/monotype Bipod which would be wrong for your gun. You should be able to pick up a Inglis Mk3 type bipod for a pretty good price in the States. Which parts are worn/damaged? If its the fit on the gas cylinder it could be that its worn or the bipod is badly worn. check the earlier post on the forum about Bren Mk1 gas system upgrades as I've a fealing the early Mk2 guns had the press fit version of the Mk1 gas cylinder (Mk2?3?) which had 2 rows of holes.

Cheers, Chris.
