'I would be interested to hear from the present owner of my old Douglas MK5 Registration no. PKP 541 which I sold to John Galloway of Glasgow around 1978.
Regards, Alf Burgess'
I have the number plate mentioned above (PKP 541) but it is on my aston martin lagonda and has been for quite a few years, chances are that if the number plate has been transferred then the bike may not be about or if it is it will have a different plate which would make the bike almost impossible to track, sorry its not useful info on the bike but i thought you might like to know
regards
