Paul Evans of the Royal Artillery Museum supplied the following information:
Buttons like this were worn by both officers and men of the Royal Artillery during two periods, from 1833 to 1838 and from 1855 to 1873. The only difference between the Officer and Soldier buttons is the burnish: soldiers' ones usually look darker than the officers' but that’s very difficult to distinguish after all this time.

My feeling is that this button dates from the earlier period of use, or from the first few years of the second period.

This is NOT a Hammond Turner (etc) button: it was made by C J Weldon, London, a company with which HTetc had both business and personal relationships. Charles Weldon was an executor of William Hammond Turner's will: William lived and died in London in the 1850s.
