We're good, Brian. Thanks.
The "Mark" designations seem to have drifted over time. In your linked post, A-Snake says "However, in period the reference was different. There wasn't a MKI until there was something to replace it. The coil spring car was called the MKII leaving anything produced prior known as a MkI. I know, a little confusing."
Also, none other than Peter Brock uses "Mark II" here:

All part of the fun!
Whatever we call them, I'm still looking for Negstad's original engineering drawings specifying a 93" wheelbase. Does anyone out there have a link to a download?
