A few comments. First a lovely car. I would very much like to have it. But . . .
Not sure why the web site URL says morgan-44-supersports - there were NO series 1 4/4 Supersports?
The answer to the SU question is easy. This was a common set up on Climax cars. The carb seen as horizontal is only one of two SUs. One is a side draft, and it vertical as you would imagine. This is a downdraft. (See Pic)
No mention of matching numbers? Possibly a bitsa? For this money, I would expect the correct bits. I hope this is a matching numbers car. I had a '39 Series 1 bitsa. Great car, but not correct.
Driving is great fun, but a bit challenging. String brakes must be set up just right or you will have challenges in today's trafic. No lights, turn indicators, etc. MOT??
Again, a beautiful car.
Cheers,
Mark
