Tinker, thanks for the reply. It's a Holland & Holland hammerless sidelock with 26 inch fluid steel barrels. Not much in the way of engraving so I'm going to guess it's a grade 2 gun. The barrel flats are marked 500 ex - and the bottom of the action is marked something like "Case 3 1/4 Inches" - so I assume it's a 500 BPE 3 1/4 inch. I'll try and post some pictures tomorrow. Chris
