Oh boy, I am very apprehensive to weigh in on this one. Why? Because I am nearly certain I'll have a number of guys tell me I am full of poopy, etc.
I chose to weigh in well, for one, I've been called worse (by better men) and two, I do have a little research experience with these supposed "40 convertible sedans".
Now, here's what I had found out about these orphans: _________________
That's right, nothing, zip, zero, nada. There was never any documentation uncovered by me nor anyone else that I am aware of that Ford actually built any of these cars.
I began my look in to these way back in the 1980's.
There were stories, photos, rumors, but no documentation.
Where's that leave us? Well, in my humble opinion, Ford did NOT create these cars. As Deuce has advised, this would be a rather simple project for anyone with good body craft skills. Plus, keep in mind that when these cars were stating to be "discovered" in the late 50's / early 60's, the "donor cars" ('39 conv. sedan & 40 anything) had little to no value. Also, the "heyday" of modifying cars. I also need to pose this question: "Why is there no record of these from 1940 forward"? They seemingly "popped up" in the late 50's.
Deuce made another very valid point. Numbers matching frame, transmission and title are all too easy to acquire and / or manufacture. In fact, this car would be simple to build - far easier than some serious restorations I've done.
The two factory equipped Mercury engine'd 1940 Fords I have had (still have one) were purchased by me with full documentation right back to build "sheets". Plus, I did research to find corresponding proof that these two vehicles were as they were purported to be.
I have witnessed first hand 1940 Ford convertible coupes, yep, rumble seat, floor shift... beautiful cars. Ford never built one but I had on two separate occasions two different guys insisting they were "real". Yes, I'd agree...real cars. No, not Ford built.
That old wives tale of these being built for the Worlds Fair... really? Does it not seem odd that Ford would have built them so late in to 1940 production (according to the number on the one in this thread)? That number puts it in the late January to perhaps mid to late February build.
Not sure if all '39 convertible sedans had a body number plate. My guess would be "yes". I have had numerous '40 convertibles and most (all but one) had a body plate. Even that one had the nail holes for the body plate rivets, plate being absent. Every '39 convertible I have had, has had a body plate as well.
Oh, one more thing on this thought... even the '40 coupes with factory equipped Mercury engines had body plates. And, in two of three that I know of, had the cowl stamped to indicate Mercury engine'd Ford.
My current '40 convertible has both a body plate and the cowl stamped to indicate this "anomaly".
The point being: Ford did tend to keep control of what they were building.
Bottom line? As has been advised previously, be skeptical, be VERY skeptical.
Ford did tend to document - very well in fact, any "customs / prototype' cars they authorized. The lack of anything mentioning this car leads me to believe (to reiterate) this car never happened at Ford or "by" Ford.
I try my best to keep an open mind about this type of thing and to that point, and in regard to this particular vehicle, I would welcome proof contrary to my opinion of its pedigree.
As a final note I truly would enjoy thoughtful responses to this thread.
Respectfully,
Mike "Kube" Kubarth
