Mystery Tram Or ?

This old photograph depicting the lower saloon of a tram being used as garden shed of shop is a mystery as to the origins of the bodywork. It bears nothing like a Blackpool or Lytham car. The only possibility is it could be two short saloons joined together with the right hand section covered by boards. In any event it presents an interesting mystery for those eagle eyed historians among readers of this blog.

Ideas please on the back of an envelope !
