Thank you very muck Lagopus. Just what I was looking for.

While it would seem that these ledgers and day books which number 8 in total, are now in private hands, one hopes that at some point they will end end up in an archive where researchers will have access to them. The Royal Armouries have the ledgers for GE Lewis, Sterling Armament Co and so on. While a number of provincial or county archives in the UK have ledgers and day books for the some of the smaller makers and retailers.
