A rare, original metal-lined cylindrical tin manufactured by F. Joyce & Co. of London, England. The tin is painted in green with black lettering and a yellow top label stating: “Successors to F. Joyce & Co. London, England – Metal Lined – Percussion Caps – F4 No. 21.” This item would have originally held 250 percussion caps for muzzle-loading firearms, a vital component in 19th to early 20th-century ignition systems. The presence of the “Successors to” phrasing places this tin post-merger or company rebranding, likely after Joyce merged with Eley or acquired successor status in the late 19th or early 20th century.
