I would say there are probably more ts59 and ts59/86lookalikes in the classics than there are genuine ts86's but it is dominated by Ransomes. Most of the others are vintage ploughs that cannot plough vintage because their tractor is not eligible due to its age.
All depends where in the world you are Tony. At one time here at Scarcroft we had no less than 13 TS86’s in the classic class with two, possibly 3 TS59’s adapted for match ploughing. 20 in the class was not unusual, in similar proportions although at that time almost exclusively running TCN’s.
It’s not that many years ago when the line up at Flint was predominantly 86’s. As you say though - Ransomes predominance - absolute and total
