The gun revdocdrew posted has pins consistent with the earlier Perkes action that would also put it in the 1892 to 1894 time frame. CJ's gun looks like the Rogers action that they adopted around the time they merged with Webley. I have one from 1895 55xxx that has the second Perkes action that Scott used. All this based on Crawford's book.
A curious thing about CJ's gun is that I've never seen the flying pigeon on the left side and the dying pigeon on the right side like that. Always the other way around.
