Lucky stroke! Charles Henry Harris' "Mah Special," a trials car built from scratch in 1950. Ford Sidevalve, Austin 7 bits, and a surprisingly pretty cut-and-shut body.

The family is searching for the car or information on its whereabouts. Hope it's out there somewhere, and didn't go to the breakers.

Well done!
You probably came across it when searching for woodinsight's Austin A30 racer puzzle?

Judging purely by the photographs of the trials action, may I hazard a guess?

Is it, "Mud and Hills?"

Good guess!
Not the answer I was looking for though..

Well according to the blurb the car was an "M&H Special".  Simple as that. M And H.
I don't know if that was an off-the-shelf special or if it was something they put together 100% themselves though.
It wasn't part of the puzzle so you get your point anyway!
Well done.
