I mis-read a couple of things. WR didn't really begin to promote the Box lock until 1877.
24 March 1877 - The Field:

Greener was absolutely one of the first firms in 1877 to go whole-heartedly into advertising and promoting the "box lock."

21 July 1877 - The Field:

Nevertheless, by 1880 I was under the impression (from Donald Dallas and others) that almost every gunmaker in London were using A&D actions bought in the white from Birmingham. (Reilly didn't get into promoting box locks until 1880.)

But my question about the action has more to do with the doll's head and the top lever. Those characteristic features are what are interesting? I'm not even sure they were protected by a patent or what that entailed. Help needed.
