Totally concur with my old mate FO.
The late and well missed, Geoff Masterton was the Rothman's team engineer and a prolific Pitts builder. In my early Pitts-ing days explained to me that the India registrations were well sought after because you could easily fit the reg in legal size on the tail and leave room for the sponsors logo.
FO can't be all that bad as he has three India's!
