Likely manufactured during the early 19th century this is a very scarce English "bag" type powder flask that bears five silver hallmarks. The hallmarks appear to be a "TC" or "TO" maker's mark, an "anchor" Birmingham proof, two unidentified proofs, and what appears to be the "duty mark" of King William IV which would date the flask from 1834 to 1837. The body of the flask is solid silver with the remaining fittings of brass. The only other markings on the flask are the dram measurements on the adjustable spout and there is a lanyard ring attached to the bottom.

Very fine, silver body shows an attractive age-darkened patina and the brass fittings also show an attractive antique patina. A scarce flask that deserves a place within a very prestigious cased set!
