Thanks to everyone for the input and offers above.

I’m now the proud owner of a lovely Original Model 10. many thanks to John (Perlin) for meeting up to complete the transaction. A complete gentleman and a pleasure to deal with.

Now the fly in the ointment, the grip on the pistol is LH.

I know it’s a long shot but does anyone have, or know where I might lay my hands on, a RH adjustable grip that will fit?
