Thanks to Joe for the following tip:
I heard of two cars for sale today:-
a) Herald Coupe
b) Herald 13/60 convertible (1970? J-plate?)
Contact: Brian Jobling - 07730454390
Can't vouch for the condition, work needed, etc., as I didn't get chance to see them close-up, so recommend any interested party contacts Brian Jobling for further information and to book a viewing. No prices mentioned.
