Original Item:  This pin secures the upper barrel band to the forestock of the Martini-Henry Rifle, all versions. This pin also secures the lower fore-end of the MkI and MkII Martini Henry, which have a lug on the bottom of the barrel for the pin, which goes through the stock. This was changed for MkIII and MkIV Martini-Henry rifles, which use a fore-end hook.

These will probably require cleaning and fitting.
