I think they called the inserts Parkerised or something to do with Parker Hale.
A lot of them were done.
Caliber may have been 300 Rook but Cartridges of the World is a great book that lists them all and give loads / pressures so you should be able to match it up to a suitable pistol calibre.
Not sure how you will go about rebarrelling / reboring it.
