Beautiful set pjaln! I have a HV .275 Rigby and visited Paul in London a few years ago. I was able to look up my rifle in one of the few ledgers that they had in house. My Rigby has a number "1" engraved on the bottom floorplate and from the ledger it showed that my gun was one of a pair of rifles ordered (in 1932 by Lord Zetland). The bottom engraving does not refer to the model number of the rifle type. From the ledger I have the serial number of the matching number "2" but unfortunately I don't own it or know if if the rifle still exists. I also picked up a couple silent slings when I was there :-)
