I bought a PUCH 250 SGS back in the early 90’s from a woman who’s husband had died a few months before , The SGS in the rare colour of Bermuda Blue was in need of restoring but was 100% original also with it came a file of all the spares bought and correspondents between the previous owner and either Riders  Autoservices or Rena of Harringay. I find them interesting because of the prices back in the sixties and communication was done by letter and politeness.

a SGS for £30 also the change of address written in pencil
Sadly no more spares
7 spare parts all under a pound each!!
I like this one because of the owners loyalty these parts are F O C  free of charge!! those were the days!
