Original Item:  Another of those rare events in antique arms:  we?ve found a small supply of the screw-in butt swivel bases that were unique to the very first Mark of the SMLE.  The base has a large integral screw rather than separate base-and-screws like later marks.  Before the SMLE, Metfords and Enfields used a similar butt swivel base, but it was machined with a narrow waist.

This group is a special prize in that most of the swivel bases are unissued, and they are all marked.  We have the following marking groups:  British Broad Arrow(7 only); RSAF Enfield manufacture; London Small Arms manufacture (two only); and the RAREST of all, RSAF Sparkbrook manufacture (only one of these).  All are in excellent condition.  Note:  The same photographs are used for all variations.
