Two Little Lenses - Agfa and Wollensak

[Fotoguy20d]

Does anyone know anything about either of these lenses? I'm assuming they were both intended for some sort of medium format folder but I'm wondering what they can cover usefully. The Wollensak is marked E.F.L - 92mm and f6.3 Velostigmat. The Agfa is a 72mm f4.5 anastigmat. It came off a Sirchie fingerprint camera that I cannibalized for it's 2x3 Graflok back and ground glass panel. But, I don't think it can fully cover 2x3. Despite the hefty difference in shutter size, they have the same rear element size (probably front too) judging by the fact that they use the same B&J flange.

E.F.L = effective focal length? I've never seen that before on a lens - What does that mean?

E.F.L. is effective focal length. I have only seen this on JML Plasmat type process lens used on my LF cameras.
It means someone sat down at an optical bench and measured that particular lens for it's true FL.

Like my 309.4mm lens.

Assume the Wollensak will cover 6x9 and the Agfa will cover 120 - 645, or 127 formats.
