aqbill,
Brian Dickof bdlltd.com is a good source for any Lee Enfield Rifle
.
Personally I think all the manufacturers of the No.1 mark III are equal but I have a preference for the LSA (London Small Arms) rifles. Walnut stocks are to be preferred if you are a shooter over the coachwood stocks found on many Lithgowrifles ( Ducking for cover due to incoming fire
)
