As an aside, tubulars, the oldest standard which size has
not changed since the 1890s, are variously labeled "700C"
(they are not; the 700 type C was developed later to
exchange wheels with the same brake height as a tubular) or
"27 inch" (they are not; 27 inch systems are larger) or "28
inch" (again, 28s are all much larger) even down to today by
various tubular makers in some weird vestigial rite.  The
net effect is confusion to riders and is not at all helpful.

As a matter of curiosity, what is that standard size called,

They predate numerical designations but originally were called 28 inch as they were a lot fatter then. Actual rim diameter is 630mm.

And now, we return to fat tubulars for 'gravel' and cyclo cross. The ever popular 23mm tubulars are about 26-1/2 inches edge to edge. Newer fat tubulars are about 27-1/2 inches on that rim.

One of my best friends (still) has an old Takara "funny bike" from the 1980's with a 24" front wheel, he had tubulars on it. Even then, a 24" tubular was special order.

 Right. That had its popular moment both in professional level machines:

 and in 'econo' versions:

I love the curved top tube design. I almost picked up a really old Pinarello funny bike a few years ago with a similar design, but the seller wouldn't budge on the price ($900, a bit much for something that would see little more use than wall art).
I need to correct myself though, It isn't a Takara funny bike my friend has, it's a Nashbar. Websearch shows it as a Nashbar Aero Sprint Pursuit possibly made Shogun. My friend thinks it was made by Takara, though anytime anyone asked him who made the frame he would reply "Takara....I think".
Here it is as I raced it in  ~1992:

Yes, the bar set-up is ridiculously bad - no one really knew what they were doing back then with aero bars.
Would you have any other insight as to the actual frame builder?
