Andy, the Raumer S had sprung crew seats and huge springs on the wheels so when a mine went off the vehicle jumped. Well that was the plan!!!
The 617 'wheels' had the fishplates painted in Vallejo Gunmetal followed by Natural Steel to try and get a used look but I think I'll have to revisit them once the shoes are on. I joined one set of shoes to see if it was possible to snap these into place after tidying up the halves. It is just possible with minimal tidy up,
The Raumer S was sprayed with Vallejo and Xtracrylic Dunkelgelb followed by a light dusting of both Vallejo Rotbraun and Xtracrylic Vietnam Green. I'd painted the wheel pads with Natural Steel only to read that the pads were rubber. They may well have been on the prototype but I don't think that's practical for a production machine, but to edge my bets I lightly overpainted them with Tamiya Rubber Black.
The swivel mechanism goes together well and was painted as per the main body with the pistons, which move, using Vallejo Silver.
