Here's the number plate still on the car.
Other experts have suggested that this is the same Buchanan that lived in Murray Bridge many years ago and was photographed by Steve R. See below.
Now remember some time back I mentioned that when we were in high school we used to go to Albert Ludgate's to see his sports car creations? He built the Capricornias. One very famous one certainly had a Buchanan body (albeit shortened a bit). That was the Repco headed grey Holden powered one that Tony Parkinson sold not all that long ago. His earlier one had a less up to date body made in Sydney I think when fibreglass was just taking off. The car that we used to go and see at Colonel Light Gardens was neither of these and the body appeared to have been from a mould taken from a 100/4 Healey. I remember it distinctly, in white gelcoat and with a grey Holden motor. Back to the picture of the door. A Healey like crease through the middle and the rest of the door looks very Austin Healey.
Now take a look at the Holden powered Triden that's for sale on my105.
The body appears to be identical to Larry's and look at that Austin Healey crease down the side. The dimensions of the bonnet are exactly the same and a fair bit different to the standard Buchanan opening. This car had its origins in South Australia in 1956. Now it's time to go back to 1956 and find out where these bodies came from. The Triden does seem to have a Buchanan looking nose though.
