Re: "real" ends where ?
My suggestion for "original" (rather than "real;" I think we've been through that debate before) GT40s is the cars that were initially constructed using Abbey Panel tubs and numbered:
101 to 112
P1000 to P1086
1101 to 1114 (the seven Mk III street cars plus the seven left over tubs that eventually were built into cars)
AM1 and AM2 (Alan Mann lightweight Mk Is)
XGT-1, XGT-2 and XGT-3 (Alan Mann lightweights initially built as Mk IIs)
M10001 thru M10003 (Mirages)
After spending over a week with Ronnie Spain in November during which we hashed through the details of exactly how many Abbey Panel tubs were built, I believe that total is 123. Note that this is not simply a count of chassis numbers, as the total of 123 accounts for instances of a single Abbey tub having two chassis numbers (1004/1084, XGT-2/1009) and situations where one original Abbey tub was used as a replacement for a pranged earlier one and picked up that earlier chassis number. In some cases the crashed tub was later rebuilt (or at least saved), giving us two cars on original Abbey tubs with the same chassis number (e.g., 1073).
In addition to the Abbey Panel tubs, "original GT40s" should include the 12 Kar Kraft aluminum honeycomb tubs J1 thru J12.
I am not sure what to do about 1087-1089, the three cars apparently built up from original Abbey sections and pieces many years after production at FAV/JWA ended. For the moment I have not included them as original GT40s but welcome discussion. I am also not including the Safir Mk Vs as original GT40s. This is not meant in any way to slight these fine cars. I know there could be different opinions about this and would be interested to hear them. I had to start somewhere and felt this was a defensible position.
