WWII Fond Du Lac VOCATIONAL SCHOOL KNIVES WANTED (West Allis)

Serious collector seeking examples of the knives made by the Wisconsin Vocational School in WW2.
These usually marked on blade as such.
They made them in Fort Atkison and Janesville too.
I am near Milwaukee, but frequently travel our great state looking for these.
I pay really well for these for my own collection! ($300-$1,000 depending) I am also looking for any documentation/photos of these knives for a research project.
Even if you have one, but don't want to sell, I would love to hear about it and get some photos to add it to my database of known knives.
Help me preserve history! Thanks for looking! email me back through here.
