As it says, looking for a magazine Lee Enfield / Lee Metford MK II bolt dust cover.
The one with the square holes for the lugs on the bolt rather that the screws of the earlier Lee Metford type.
I am planning on building a few for my rifles and maybe extra... I need one for a sample to work off... I've drawn up a paper pattern of one that I borrowed off a re-enactor that I worked with, but there's nothing like actually having one right there when you're fabricating something.

Please contact me with prices plus freight to Dunedin, New Zealand.
You should be able to ship it as a machinery dust cover... Which is what it is really.

Regards
Kiernan
