Quite nice shame its not very original.
Wrong wings (late series 2A) , colour , wheels, door hinges and mirrors.
Is all the capping's painted over?
I would say about £1000 to £1500 depending on if the buyer is worried about the above or not, and how well the mechanics are.
Also what's the chassis like for rust and the bulk head?
Ps
On a landy of this age mileage is not that important
