A trawl through some pictures from the late '50s and early 60s produces a few AMW bodies, not all on Buckler chassis:
1. Roy Billington's Elfo Special at Muriwai Hillclimb late 1958 (not a Buckler apparently)
2. Vic Simpkin's Buckler at same event. Judging by ill-fitting bodywork probably same car as below,
3. Club Circuit meeting January 1958 week after NZIGP. W (Rick) Harris ran #2 Buckler at the GP meeting - looks like same car with a "0" added. Note fit of bonnet.
4. Alwyn Marshall at an Ostrich Farm Road hillclimb 1962.
The Billington car appeared at a "GP Show' at the Newmarket Car Park before the 1959 NZGP with Australasian Motor Works advertising around it. I have a dodgy photo of it - flash didn't work or something.
