South African No.4 socket bayonet frog. (No ref.)
Brown leather frog for the South African No.4 socket bayonet. Excellent brown leather frog with 7 brass rivets and washes. Brown leather strap with steel buckle and roller. Front differs from the No. 9 frog by an extra stitch to hold the No.4 bayonet.
Excellent genuine example.
This frog still fits the South African No.9 bayonet.
