well another small update- I noticed from my references that the drive wheels should have two nuts between each spoke i presume for changing the rubber blocks as they wear out, so out came the hexagonal punch and die set had to scrape off the paint to get good adhesion

Then repainted them also got the second run of track assembled then painted both first with a red primer, then a coat off red brown and then a coat of earth colour before painting the track pads with vallejo dark rubber will leave them to harden for a day or two then finish with mig pigments
Cheers Ian
