Webley oil can

[Troubledshooter]

Looks like a repro label, sized to fit one of those Singer sewing machine oil tins from the 1950's/60' ?

On the other hand it could be a one-off prototype 'can made for Webley by Singer, and as such worth a fortune? Tricky one!

I think your suggestion of it being a re-labelled 'Singer' oil can could well be correct, Chris, as I have a similar 'Singer' can on the shelf.

As for it possibly being a one off prototype, I very much doubt that as the 'Webley' on the top is wrong, being curved on the top edge of the logo instead of the bottom edge.
It's a pity there is no rear view.
