Ceconite / Randolph product dope & thinner surplus

Having finished my J4A project, I still have roughly 7 gallons of Randolph product butyrate thinner, 3 gallons of Randolph Butyrate original Piper Yellow (Lock Haven yellow) dope, 5 gal of butyrate clear, and 5 gal of butyrate silver left over which i would like to get rid of. It is located in my hangar at Shell Lake WI or could be brought to Minneapolis MN. Non of it can be shipped by common carrier since it is considered hazardous. Any serious offers?

I also have three 7/16 inch thread J4 lift struts (two main and one rear) and fork fittings that have only about 15 hours on them. They have been carefully aged under dry conditions for 25 years. Presently they are located at Shell Lake WI. Again is anybody interested?
