That'll be a great project Andy!, keep it posted
A friend of mine has a '56 Series 1 (86") in his workshop that he's owned for almost 25years! (he's the same age as me; 39)
It's complete & was a runner until about 12years ago, but then he put it into hibernation.
Now he plays with his Austin Gypsy & (3) Atkinsons.
He keeps saying he'll drag the old girl out & get her running again. I remember its first road run after he passed his driving test(when it had a V8 from a P5B under the bonnet :D :D )
