Cromwell at the Blue Boar

Very tricky plywood puzzle with widespread colour line-cutting and large sections of push-fit pieces. This is very much akin to the style of the Salmon-Academy Super-Cut range, see In the Days of Old as an example. In the absence of an original box it is currently categorised as of unidentified origin.
The painting is by the British historical artist Ernest Crofts (1847-1911).
