Thanks for the info I really appreciate it. BrianNice old button, but I think “livery” rather than “sporting”. I believe I can see a “torse” (a twisted piece of silk) below what I think is intended as a crocodile and, as a generality, livery buttons have their crests resting on a torse but sporting buttons do not. They tend to have a patch of grass, a log or something similar, if anything at all. The torse is a heraldic device used when the crest is separated from armorial.
If it is livery then there are several families who used a crocodile as a crest. Try Googling “Rossiter family crest” for example, since that's the most likely possibility.
The maker is Hammond, Turner & Dickinson (names in that order) of Birmingham, England and they operated under that name between c.1790-1823 before changing name to Hammond, Turner & Sons.
Thank you. BrianI pulled these from other TN threads...
