I'm belaboring this line but here is explanation for the comment by William Evans that this 20 bore bought by Jacob Wakefield was part of "a six gun order." Williams Evans explained that Wakefield did not order six guns. Rather Williams Evans sent a bundled order at one time from six separate individuals to "the factory" and at that point the (ordered) six were serial numbered. The six guns had been ordered by separate individuals from William Evans; their names are listed in the ledger. So Wakefield ordered one gun #5210 and traded in #6050 as credit (perhaps a deposit on a separate order?).
I have no idea who made William Evans guns at the time or where "the factory" was located. Previous posts (trw999) indicate Birmingham as a source of "white guns" and in particular Webley Scott.
