Webley did supply a non valvespout oil can prior to the introduction of the latter but that was of a different shape and I have only ever seen one in a private collection. Initially the company recommended oil bottles of Neatsfoot oil, which were presumably unbranded or generally available commercial Neatsfoot oil.
There is no provenance to suggest the oil can under discussion is a genuine Webley item, so I'd suggest caution if anyone is thinking of bidding. Personally, I shan't be bidding on this one.

Currently looking for Baikal Makarov pistols with the following prefixes to the serial number: 98, T01, T09, T21, T22
Prefer boxed or cased but will consider loose examples too.
