You are bidding on one of these .303 Enfield Lithgow rifle Pull throughs.

Note: The cord is an Australian Military refurbishment, is dated as WW2.
Australia did not make .303 Pull throughs after WW2, we made an enormous amount in
WW2 which satisfied our requirements until the L1A1 SLR was adopted in the 50's.
The pull through is about 4 feet long and fits into the butt trap of the No1 MkIII or 
No4 .303 rifles.
