With some difficulty some of her early images have (likely) been dated; any with the flower embroidered skirt are c. 1885 (before she received her 4 Lancasters in 1887)

The image holding the Smith is 1899

There is a thread on the LCSCA Forum where I have posted images of her shotguns; one of her sitting probably also dating to 1885 - 1887 shows what appears to be the Scott forend lever latch, and another studio hunting scene very likely with a Lancaster back action sidelock. There are 2 images of another sidelock that I can't ID.
Please add your thoughts regarding the makers
