Hi, I believe the bike I bought is a 1969 model but it’s almost impossible to tell since there is no frame number and the bike has never been road registered. I’ve searched everywhere for Dalesman information but it’s fairly sparse. This bike has been heavily modified over the years even to the extent of fitting a Yamaha engine, the frame has been modified to take the engine and will have to have the correct engine mounts replaced. I’m hoping to source the correct Puch engine but it’s proving hard to find….. Think this may be a long term restoration. Good luck with tracing your old bike and thanks for the information.
