Yep... bit annoying that out of the five frames only the "Curly Cut" has such small proportions.
There is a chance that this frame has tapered tubes, i know Mark Stevens 1947 Curly Cut frame turned out to have Taper Tubes, though to be fair it was a bigger size.

I would be all over this, if it wasn't so dam small.
