That's what I would suspect as well. 43126 is definitely a CC, not a CX. Note that on many late CX examples, the first digit "1" of the serial number is stamped rather weakly, and often barely visible, so this one might be 143,126 instead.
Also, there is no CX with leather-covered back. Only early CC examples had leather on the back part of the rotor housing (up to S/N 20,xxx, 1939). There is a reason behind the change: the front-side depth of field table starts with f3.5
, referring to the Wollensak and Ilex Tricor f3.5/35mm lenses. In 1939, Univex introduced two new, more advanced lenses, the f2.7
/35mm Wollensak Tricor and the incredible f2
/35mm Wollensak Hexar. Therefore, a second table was required, stating the additional depth of field values for f2 and f2.7. The change was made at the same time the CC-1500 was introduced.
