No answers, yet, but we try on this Forum! Maybe a bump will help!! Started life as N1613Z in 1962 to become G-BXRH, 12/10/97, to become M-BXRH 21/6/11 and now N185RH from 8/9/13. Photo shows aircraft in its current scheme which flew to Oshkosh last year, presumably from its base in the Isle of Man.

Sorry, missed HB-CRX which came after N1613Z. Presumably the owner is still Robert Holmes.
