The 55 is in fact a 55 Riceland diesel with the high arch front axle so not original to the UK
I bought it 2-3 years ago from a dealer in Conecticut on the basis of what I beleived to be very honest descriptions of it in photos and over the phone. It turned out to be a first rate tractor needing very little doing to it - the main jobs being to re-line the brakes and re-wire the electircs. Very good starter even in cold weather.
55Ks were imported to the UK and a handful survive to this day. A few have been imported in recent years from USA and Australia, the Aussie ones all being fitted with what I consider to be quite ugly rear wheels cast in Aus. Some of the original imports have been retro fitted with Perkins P6 diesels to finish their working lives in a more economical manner but I think it devalues them
