Well there is #004 for sale in Belgium(?) which is RHD. Unsure which green it is from the terrible photos. Maybe Le Mans or Goodwood?
Then there is SteveTD's Shot Silk supercharged car. Looking back on the '260s SOLD...' statistics, the last time I saw a RHD real green car come up for sale was just over a year ago, and then only 1 in the whole of 2018 (plus 1 Shot-Silk ZT-T and 1 Typhoon).
