I'm going to stick my neck out and say it's more likely a Westley Richards action from the first two or three years after Anson & Deeley took out their patent. I've only ever seen the round/cylindrical ends to the cocking levers on WR actions, also the Westley Top lever arrangement was only used by them at that time. Suggest you strip carefully and look for other patents identified.I have a Thos Turner from same era which has 5 different W.R. patents listed on components.
