This is a hard to find brass mk 3 oil bottle for the Long Lee and Lee-Enfield rifles of the day, identifiable by it's distinctive rounded bottom. They were in use from 1899 to 1906, before being replaced by the flat bottomed mk4 which stayed in service till WW2, before brass was replaced by bakelite and plastic. This example is in great condition, no dents, complete with washer and attached spoon. Broadarrow and inspection stamped on the base, along with Enfield maker stamp of EFD.
