So, my 1889 131xx Purdey (SBA) rifle has a Anson & Deeley use number of 7326, while my 1890 135xx Purdey rifle has a A&D patent use number of 9561. This gun has a use number of 11349, which can't be very much newer than my double rifles.
So at this point we know it's an original Purdey from the very early 1890s.
The 16477 is totally wrong as confirmed by the Purdey records.
It can't be proven at this stage that this gun was a DR or not, until the real Purdey # is found, possibly inside.
