Now that the wiki is out of the way, I’m uploading some separate datasets to Github in case they’re of any use for anyone else’s research. To start with, I’ve added a catalogue of manuscript volumes created by the Ordnance Office in London recording contracts, deliveries, and issues of equipment for the New Model Army from 1645 onwards. This is obviously relevant to military history, and it is potentially very valuable for business history. The names of suppliers and the descriptions of equipment they supplied show what someone was actually trading in. This can be obscure in 17th-century London because women were usually described by their marital status, and men’s occupational descriptors could refer to their actual trade or livery company membership, which were often not the same thing. Matching contracts, deliveries, and warrants and receipts for payment can sometimes reconstruct a whole transaction, showing not only who supplied what, but the time from contract to delivery to payment. Gerald Mungeam published the largest collection of contracts from the London Museum (and scans of the original manuscript are now free to view at their website), but the rest of these records are less well known and have not been used to their full potential for business history.
