There is a chap on ebay selling all these on CD for a couple of £. I have picked up one old catalogue but basically Krause is boll**ks and just a general reference.
Try the Fitzwilliam museum in Cambridge.I am aware they have an extensive library of auction catalogues I'm planning a visit once I can establish what they have and what I want to see. Mrs Peter and the girls will happily spend a day shopping before I buy dinner. Fitzwilliam site is not the easiest to navigate but a phone call has worked wonders.They have some smart people working there.
When I was working at Waterloo by train back to Suffolk left from Liverpool Street. A couple of other lads used Liverpool Street which is a stones throw from Brick Lane and Green Street. You had to take your own beer into the many Curry houses.We ate there at least twice a week for about £5 per head Smashing grub.I also had a Pakistani clerk and his mother often sent me a container of curry for my lunch.
I've gone for 10 bob notes and £1 notes. Replacement notes are the collectable ones. I started out with an unopened wage envelope from 1940 it had 2 10 shilling notes. I also have an album of cheques.....sad bugger I am.
