Hans - I feel like I've died and gone to nut heaven!
I plan to go through your collection and compile all of your "Head-Markings" into one or two sheets. Once this is completed you will be able to tell which ones haven't been included and or are missing. If it isn't too much trouble I will then request that you take additional pics of those I have missed so they too can be included in the collection.
Please keep in mind; all I am looking for at this point are head-markings. Part numbers/locations are a whole other journey. If its okay, I will lean pretty heavy on you guys; including George, Dave and others for both those topics once this head-marking bridge has been crossed.
Again...big time thanks!!!
