Hello Kevin and welcome
I had one of those Sachs powered sets a few years ago and like a prat moved it on
Not sure now how to change voltages but I think there's a few sparkies on here who may be able to advise you...
Wristpin, I like that set of yours...
As some of you will know I am a collector of most things made by Tarpen Engineering of London
These signs popped up on ebay and were secured for a sensible price
They are original signs from the fifties owned by a chap that used to work for Tarpen, they have plenty of patina
and will compliment any of my Tarpen displays exceedingly well
Chuffed is an understatement...
