Dave, thanks for the feedback. The fact that it is an f9 does not worry me as I have an f9 150mm G-Claron and an f8 120mm Super Angulon and have never had any problems focusing or composing.
The lens has arrived It is indeed a compact lens. Mounted in a Copal 0 shutter and takes a 52mm filter. It looks to be a single coated version but is in great condition.
I have now mounted the lens on a Wista Lens board and ready for some test shots with my 4x5, 5x7 and freshly repaired 8x10. Film holders loaded, so off I go
