Ash - follow LesLeeSpeed's advice and call Dicksons direct

For the cost of a phone call (even international rates) they will give you the info from the sales ledger

I have called them twice, (about Alexander Henry falling block single shot rifles, of which they hold the relevant info) and got an immediate response about the sales ledger giving date of sale, who bought it, and most importantly the standard of the rifle and the details of it

Good luck whatever happens
