Terrier Antiques at Hebden Bridge has dated this piece to the 1890s.
The numbered pegs are randomly inserted into the cartridge, number side down.
Place finders were very popular from the 1900's and are making a resurgence today, with many shooters looking out for good antique examples.

There is one closing clasp missing but it still opens and closes as it should and stays firmly closed, the silver needs a good clean but we have left this alone for it's new owner to do or leave as it is, the fan mechanism is in perfect working order and all the pegs are present, original and clean.
Size: 52 x 30mm when closed
Free postage and packaging is included in the price of this item.
