| Description | This Day Book, which may also have been referred to as “Book Z”, records sales of goods and parts by the engine business to other businesses or employees at Soho Manufactory. Customers include James Watt & Co. (the copying press business), Soho Mint, Matthew and Matthew Robinson’s Boulton’s various Soho concerns, and various overseas mints sold by Matthew Robinson Boulton. The book is arranged by account, in the style of a ledger, but each account was updated day by day in the style of a day book. Entries were posted to the Engine Day Books (Nos. 1/34—1/42). The series was continued – some of the accounts are noted as being continued in a “new book”, but this is now missing. The Soho Day Book is indexed. |
