Parkhurst shotguns were made in England by J.P. Clabrough and later in Belgium by Neumann, Janssen & Dumoulin ( SPI ). In 1899 Neumann Freres, Janssen fils & Cie, and F. Dumoulin & Cie formed Syndicat des Pieces Interchangables. This was done to standardize the manufacturing tolerances of sporting arms. Shortly after forming, they turned it over to Fabrique Nationale. Not surprising as many of them had been founders of FN.

Parkhurst is a brand name used by H&D Folsom Arms Co. They were sold in the Schoverling, Daly & Gales catalogs. If you go here, you will find an image Researcher posted of the catalog. It shows a 28ga for $10 and a 44XL (early American version of the .410) for $10.80.

If they are in decent condition, I say "Go for it."
