The Patt14 No1 I suspect was converted from a Sparkbrook LE1, probably post 1898 manufacture. It became a ConDII in 1905 and then a Westley Richards conversion Patt14No1. It's Aussie markings have "33" next to them, may be the year it got here? It's all original, all matching, as it was in 1915 (plus a few bumps and bruises)
My Short .22 II was converted from an 1899 Sparkbrook LE1* 1. Interesting markings on the butt socket with both the 1* and the 1, neither struck out. Pic below. Also on the recycling side of the discussion, here's the underside of the rear sight. No less than four serial numbers!
