I use a 12" Dagor on 7x17.

For 7x17 I use:

600mm Fujinon C, f11.5, in Copal #3 shutter
450mm Nikkor-M Sinar f9, in Copal #3 shutter
300mm/12 inch Wide Angle Wray f6.3, barrel
300mm/12 inch Gold Rim Dagor f6.8, in #4 Ilex shutter
273mm/10 ¾ inch Wollensak f6.8, in Pi-Alphax shutter
250mm/10 inch Kodak Wide Field Ektar f6.3, in #5 Ilex shutter
I had a 210mm SSXL but felt it was too wide for my vision and sold it.

My most commonly used lens is the 300mm Dagor.

For 8x20:
420mm Apo-Nikor
600mm Apo Ronar

I have tried the 14" Kodak Commercial Ektar, but it will NOT cover 8x20.

If you like the 240mm on 4x10, the Nikkor 450mm M would be a great starting point for a 7x17/8x20 lens. It will cover with movements, is very sharp and contrasty, multicoated, in a modern shutter, takes commonly available 67mm filters and is very affordable.

A few more:

305mm Computar

14" Goerz Trigor

360 f5.6 Symmar in Compound or Ilex No. 5 shutter - late samples in Copal No. 3 shutters were labeled 355mm with a max. aperture of 6.8 (limited by the "smaller" shutter) - not this refers to the single coated convertible Symmar, not the newer Symmar-S

The 360mm Rodenstock APO Gerogon covers 7x17. I've heard it also covers 8x20, but I haven't tried it.

Ditto for the 360mm W.A. APO Nikkor. I know it covers 7x17, but don't have an 8x20 to try it on. Note, this is the W.A. APO Nikkor, which is pretty hard to find. It's much less common than the standard 360mm APO Nikkor (which definitely won't cover 7x17/8x20).

In a longer lenses, the 760mm f14 APO Ronar Compact covers with ease, as does the 760mm f11 APO Nikkor.

I use for my 8x20
16.5" Goerz Apo-Artar
19" Goerz Apo-Artar
24" Goerz Apo-Artar
30.5" Apo-Nikkor
All covers this format without problems.
The next will be a 305 or 355mm

The next will be a 305 or 355mm

The 305mm G Claron covers 7x17 with a bit to spare. I haven't tried it on 8x20. It may just cover. It's reasonably small, light (Coapl No. 1 shutter) easy to find and inexpensive.

The 305mm Computar will cover 8x20 with plenty to spare. Unfortunately, it's a lot harder to find and much more expensive then the 305mm G Claron (Quality Camera currently has one listed at $1995.00).

If you move up to 355mm/14" the options become more plentiful. The 355mm G Claron covers 8x20 easily as does the 360mm/355mm Convertible Symmar. The latter is big and heavy, but is available in shutter (Compound or Ilex No. 5 for early samples, Copal No. 3 later).
