I wish I still had my MG TA, 1935.
Factory "MG" registration (MG6139), larger finned brake drums, finned aluminium rocker cover and sump pan, three nipples each side under the bonnet, with grease pipes leading to spring hangers and other chassis bits. Plus the fly-off handbrake on the passenger side, just at the right height to touch up the knee of the girl in the passenger seat. Those were the days of Mary Quant and the mini-skirts, with the later introductioon of tights for the girls. No doubt some of our ladies will remember those ill-fitting monsters!
Not to mention the phosphor-bronze trunnion bushes (unobtainable in early '60's when the car was only 30 years old (older than me at the time!). New pair made by local precision engineer to keep car on road. Also the spring-loaded knuckle-joints in the steering, causing the car to be failed on it's first MOT test due to a description of "excess play" by a mechanic who had never seen the type before.
And, yes, "horizontal refreshment" in the words of Lord Montgomery, was possible, even with the hood up, provided one kept one's ass away from that fly-off handbrake, especially if parked on a hill!
Those were the days!

Colyn.
