Ken H , Paul B and others the photo - reposted below
The Cars from closest to front of the line-up ;
Austin Healey white LHD [ not a 100S - as they were all right hand drive when built ]
From the other photo of the car a 100/6 or early 3000
Second car yes looks like a 100S RHD and fuel filler in correct place - if AHS3804 Engine # 222736 body # 64 was sold to Ed Bussey -as mentioned by Ken - through Ship to Shore Motors West Palm Beach,
USA dispatch date stated as 19 Nov 1955 - by Geoff Healey in his books.
The third car in the photo looking from the back - a Triumph either TR2 or more Likely TR3,
Then a mystery car
The front car in the line or last car another Austin Healey probably 100/6 or early 3000. 100/6 were 1956-59 first 3000's in 1959
Edited comment : Ken have " borrowed " the photo's for my archives and the "Austin - Healey " thread.
I have from the Geoff Healey books the full manufacturing details of all the 100S including the Experimental [ Record Breakers ] and the 5 works Racers
