From David Baker`s excellent book on Thomas Horsley.
Ellis & Scott patent No 2816 was by taken out by Richard Ellis gunmaker and Henry Scott ,gunlock and action filer in 1879,Subsequently bought by J.P. Clabrough in 1881/2 who protected the patent in U.S.A,as no.252703 in 1882.
Horsley abandoned the action pretty quickly after a number of catastrophic failures with high profile customers!!!!
Hth.

Much more detail is given in the book ,which is an excellent reference on Horsley guns but also gives an insight to the workings of the trade .
