Yes, I assumed that the parent company's serial numbers would be continued at the US spin-off–especially since the list started at 70001. Clearly this is not the case. The relationship between German manufacturing plants and their US expansion plants (pre-WWI) was complex and different in each case. Ah well, it was a very quick search. I'm glad better information was available.

Somewhere, I have a link to what seems to be a reliable list of the German numbers; I'll post it as soon as I find it.

I've seen worse looking lenses clean up to be just fine. The Aplanat is similar to the Rapid Rectilinear, both can be surprisingly good.
