Hello,  I would like to start collecting Karl Griesbaum whistlers.
I have dug through the Archives and have found much good information
but missing is a comprehensive catalog of the many varieties produced.

I am especially interested in learning how to identify what years
certain models are from.  I am also interested in restoration
information since I would eventually like to become adept at restoring
these myself.

If anyone has catalogs, photos, or additional technical information
(besides the ones currently in the Archives and on the 'Net), can you
please share.

Thanks,
Don Haga
