Couple more leather ones:

Lovely Alexander Henry example, gold embossed on red leather.

Next one is not the best pic, again, had to crop it from a web-image of a cased gun. Would suit my little plain-engraved 12-bore boxlock by that maker.

Charles Hellis made much of his cartridge loading as mentioned on the case label.
A photo of his premises reproduced in one of Boothroyd's books shows same emblazoned across the shop-front window!
