Thank you so much for the Springer information. I have been going through my Dads canal phots and waterways world collection that I inherited. It brought back happy memories of the Llangollen canal and our shiny Dawncraft 22 purchased from Egg bridge marina, around 1976. We soon realised we needed a steel boat so one Saturday morning we arrived at Springer engineering with boat trailer and went home to Hardingswood junction with a 26’ hull. An old man once told me that Sam Springer had been trying to build pre fabricated houses at one time has any one else heard this?
