I spoke with PM this afternoon and I will be stocking spare parts for the 121's, probably in early September
I will have them at the Bray Wheelers gig for anyone local and should otherwise be contactable via DM here
Spares are also available from PM for warranty work, but bear with him its a one man show and things move a tad slower that expected
The issue with the vac pipes is that he went for scale pipes and obviously it wasnt his best decision,
Any chance of a pic showing the white metal versus the MM ones?
Spare motors are available not sure about the boards, I will let you know when I hook up with PM.
