[LargeFormat] Tessar, Nettar, Novar...

[Guy Glorieux]

Can anybody rank the three lenses Tessar, Nettar and Novar on a Zeiss
Nettar 515/2 Folding rollfilm camera?
I've read some good comments about this camera as an inexpensive vintage
6x9 that can still give good service.  But I haven't been able to find
any comments about the three lenses that were mounted on this camera.
What about the differences between the Pronto and the Compur shutter?
Thanks in advance,
Guy
