In 1998, I toured England for 4 weeks and pre-arranged my tour so I could attend 16 different TR groups at their local monthly meetings, usually (always) in a pub.
I met a chap at the local group meeting of the North London TR Register group. This chap had a midnight blue TR5 and he could remove his steering wheel - much as in a Formula 1 race car. It took a key to permit him to unlock it from the column and once he had removed it, he could re-lock the clamping device onto the end of the steering column. I thought it was very interesting.
Also, on the rear deck he had a rack for his racing bike and when I went into the crowded pub, I immediately knew which chap was the TR5 owner. He was the only chap there dressed as if he was ready for the "Tour de France".
As long as he didn't forget to put the steering wheel back on - as Damon Hill once forgot on his Williams and was penalized.
