One of the nice things about the BHF is that it can unearth information that is not mentioned by previous persons who have looked very closely into certain subjects. Here we have a clip from 1914 that mentions a Henry Jones, the “King of Birmingham gun making” and yet he does't seem to get any mention in the “gun trade" information which is easily available. In the clip Henry Jones is said to have invented the self-acting revolving pistol in 1835.
However there is the another clip from 1835 that reports a Charles Jones of Whittall Street demonstrated the pistol to the Turkish Ambassador. There are references from at least 1833 of a Chas Jones, gun maker and medalist at 16 Whittall St and St. Mary's Square, and in 1862 at Alma Street. There is also a mention of a Henry Jones in 1849 at Park Road, 1855 at 6 Court Lench St, 1873 at 41 Islington Row, and 1890 at 10 New buildings Price St.
Of course Charles and Henry could be brothers, or father and son, or even the same person.
In the first clip it also says that in 1858 Henry perfectected a double grip action breech loader. There is a mention of a “Jones screw grip action, a patent 2040 of 1859” on the vintage Gun site below
The Henry Jones screw grip is seriously under-valued.

Looking on further vintage gun sites it reveals....
“The screw grip was first patented in Britain by Henry Jones in 1859 - an "underlever screw grip for breech loading actions" - typically referred to in the trade as "Jones underlever" or "lever over guard" as Lagopus correctly stated. The Jones is a screw grip action. It's primary (and only) locking system is a screw grip.”
So we have the basis for anyone who has an interest in vintage guns to delve further.
