I wasn't sure whether to post here or in the location thread, decided to start here !
The NWT hold this photo in their archive and the wherry is described as heading upstream, approaching the junction with the New Cut just before the Reedham railway bridge. However the railway infrastructure doesn't seem to fit that location ? I did wonder about Whitlingham but again it doesn't seem quite right. Another option would possibly be Haddiscoe as there is plenty of railway infra there but again I can't "make it fit".
Any alternatives or views supporting any of these locations ?
