Kind of an inside joke. My GT40 has a Mark I chassis, built by David Brown. It was completed by Safir in Ohio and got its chassis number from them- it has Safir GT40 uprights and some other Safir items in it as well. I'd forgotten I put that in the profile. I probably ought to change it. Interestingly, because David used original drawings to build the chassis, it has the old-style suspension dimensions, not the later ones worked out by, I think, Alan Mann Racing.
Then again, it's "one of one".....

Maybe I'll just leave things as is....
