I found this image, while reading a number of pages covering the firearms of the world of Sherlock Holmes - quite a bit of that, speculative.
As various “morale patches” go, I thought this one combined cheekiness, and some pride, for this particular unit. The image was rather large, and in .png form. I reduced it to 45%, and in .jpeg form. If anyone can benefit by the larger image and format, just let me know.
