Sounds very interesting. Iv had a couple of Parker Hales and currently have a Muskatoon which is a great rifle to shoot, always brings a smile to the face of anyone shooting it.
Sadly Iv never owned an original but seem to remember there where a few "wall hangers" that where made with working triggers etc but had a small hole drilled in the underside
of the barrel. Mine has Parker Hale stamped on the metal and a round stamp on the stock. I doubt if originals where ever made for anything but shooting but best to get it checked
out before using it. Would be great if its un fired original.!!
