For a given focal length, say 10", I guess the Aplanat or a Rapid Rectilinear will have a bigger image circle than a Petzval?

That seems to be the case for me unless I confused the 2 negs I made of the same shot, one with a 10.5" Ross 1840s vintage Petzval, the second with a Grubb B or C (not sure which it is) Aplanatic of similar perhaps slightly longer focal length. The Ross produced an 8" circle on my 8x10 film ; the Grubb covered it without any fall-off.

I guess my question is: did I identify them correctly?

I can't get over how sharp these 155-168 year-old lenses are!!
