Cabrioman,
The commission number does show overdrive which matches the switch on the column. It looks pretty complete and not bad for a car that's been sitting.
I do have to ask what the large cannister and assembly is in the bottom right-hand side of the first picture (would be above the fuel pump). I've never seen anything like that before on a TR4 or TR4A. It looks like a vacuum cannister and it's been connected to an additional tap in the intake manifold. It looks like a vacuum-assisted brake booster since there also appears to be a brake line going in and out of it. Not something I've seen so I'm interested to know if this was a factory option or something someone added?
