21 July 1877, "The Field" - First Greener advertisement for the A&D. Don't know what exactly "to use" meant but Donald Dallas contends that no gun maker outside of Birmingham save for one exception in Edinburgh actually "made" the box lock. (Since Greener had a workshop in Birmingham - perhaps he is an exception?)

I very much doubt if any London maker built boxlocks. They were so easy to buy in, either finished or partially finished from Birmingham that there was no point in going to all the bother of tooling up. The London gun trade specialised in sidelocks and Birmingham boxlocks. The only makers that I know who either built or partially built their own boxlocks were Jospeh Harkom and Daniel Fraser of Edinburgh. Both their designs were unique and differed from the normal trade boxlock.
