Over the last few evenings I've made great progress, culminating in me actually taking the body off the Herald.
I'm pleased to say that after a quick inspection the chassis looks in very good condition, having previously been restored and welded in a few places. One of the chassis outriggers (sides) has been replaced too.
All good news, as this is work I don't have to do!
Many thanks to Dad who helped lift off the body and carry it into the garage.
