This one is for the experts. Is the chromacor simply take a achromat design and convert it to a Petzval?

No. Chromacor is a zero-power device. Entrance
and exit surfaces are flat; internal elements
appear cemented. It uses thick glasses with strange
dispersion properties to delay/advance focus of
different wavelengths. There is also some correction
for sphero-chromatic aberration. Some also have
correction for spherical aberration (O and U models).
