And the R400K is a VHPD with Roller TBs, MBE ECU and a different loom - if you think there are any other differences I'll be interested in knowing what they are.
I realise mechanically the R500 is more exotic, but I think the engine loom is different to the standard EU2 k series, and the point I was making (obviously poorly ☹️ ) is that it is the same as the R400 loom.
ETA - I guess the question is what does the OP have - an original VHPD on swan neck bodies, or a later roller barreled version....
