A mate has acquired this rifle for me from a local collector who is clearing some stock. It has a hexagonal barrel, not sure of caliber, likely around .577, may have a leaf express type rear sight, patch box, not sure if it has a hooked breech, does have the barrel secured by a singl wedge. Under rib with two ram rod thimbles, iron ram rod which may or may not be original to the rifle. I did handle it some time ago and found it well balanced and points well. Lock looks Pat 53 type but with flat sided hammer which closely resembles the military style pat 53 hammer. I will see the rifle in a couple of weeks as I am away on swing in the mines. Will post photos of it asap.
