Seems to be a few of these surfacing their rare heads these days. Are they collectable? They should be... In Europe Autodelta built ones certainly are. I believe the Aussie cars have the same spec as the European ones but were converted using a kit, in period by ? Ray Gulson, John French or some local dealer. This one lacks the original spec 14" or 15" Simmons that were fitted to cars in period but has the correct dash - mounted boost guage and crude bonnet vent. If I had more space (and $$$) I would buy it and restore it. I'm sure these will be collectable some day....
