E.M.Reilly & Co; exhibited at the U.S.International,Centenial exhibition of 1876,held in Philadelphia. According to the "official catalogue", their exhibit included Breech loading guns and express rifles. A total of 20 leading British gunmakers of the day participated in this exhibition.[ The exhibition ran for 159 days and attracted 9.9 million visitors!]There is little doubt that E.M. Rilley was,in the beginning a bonafide gun maker in the best traditions of the London trade.I recently examined a cased, mint, pair of Reilly percussion pistols the quality of which was second to none!
In their later days they did develope into a wholesale gun makers and dealers. Records show that their business was established in 1841 and that it closed in 1917.
