Well it was in the local gunshop for over 12 months but I finally bought it. A left-handed, fast twist muzzle loader (as near as I can make out 1:18") with spare 12ga barrel for the princely sum of $AU150. The makers name is "A. J. Walker" and I have no idea where it came from? It came with a Lee boolit mould calibre 0.446" so I spent the day casting some minnies for a weekend shoot!
