Cannot find chess books!

While holidaying in England has been pleasant, the one thing I've missed is finding second hand chess books. A planned trip to Hay-on-Wye failed to eventuate, and now that I'm 'oop north', I haven't seen many second hand bookshops.
Instead I've been reduced to reading through Rupert Jones' chess collection. One interesting volume was a bound set of British Chess Magazine from 1920. As a past chess magazine publisher I can sympathies with the editorial team who were extremely worried about the magazine finances, and the level of subscriptions (at one stage as low as 500, although it was soon after World War I).
There were a number of reports from British chess, as well as mention of events like the Victorian State Championship, and a Melbourne Chess Club v a Sydney Club telegraphic match.
At random I've picked a short game where Black tries the Philidor Counter Gambit and quickly becomes unstuck.
