Was shown this by LesLeeSpeed on this forum. Bought it a few weeks back, arrived at the dealers 2 days ago, went and had a look yesterday and snapped some pics. Should be picking it up this coming week. Fortunately the dealer happened to have 15 cases that fit (bit sloppy, but will fire out). Ive got a .44 magnum expander and neck sizing die on the way.

The barrel reads "R Jones 9 (or was it 29?) Chapel Street, Liverpool"
64 bore with black powder proofs. Slugged the bore and it measured .429/430. So going to get some molds for the .44 magnum. Going to try and work out a trailboss load. May be getting some 300gr paper patched bullets to try out. Should be fun. Shes tiny! Has a damascus (just etched?) barrel too. Bores alright, slight pitting near the muzzle. Will see how it shoots. Hopefully get to take something with it in the upcoming months.
