Argo, I looked at the proof marks on my 8 Bore double rifle and they are London marks. Reilly could have made his own guns at that time, but my rifle looks almost identical to the Holland 8 Bores and Manton 8 Bores. A lot of the Holland rifles of that period (before 1893 when Holland built their factory) were made by W & C Scott. Holland or Reilly might have bought partially finished guns and finished them in their London facilities. Roberts (an out source stocker) also did a lot of stocking for Hollands and the trade. By the way, I am selling the 10 Bore Reilly double rifle to a good friend. The quality of that rifle is equal to any Purdey or Holland that I have owned. Thanks again Argo, and for your military service!
