Dear Mark,
With a smile I'm looking at your videos.
I myself am also about to start a restoration project on a old R11 pump.
A brief question for new (I know more will follow once I start), but where do you get the spare parts?
I know e.g. the "SLS shops and MB shops" have seals etc. But if I need more detailed components, where should I look.
Curious for your answer.
Best,
Bart
