Hi arf1,
there is some information here:
http://www.nkilgariff.com/ under the FH Grubb link.
Hopefully it will help you in your search.
I also know for a fact that the uk national cycle library
http://www.cyclemuseum.org.uk/ has pdf scans for catalogs ranging from the 1930's and 1960's, but you have to become a member to log in.
Good luck!
