I have an antique Hardie Orchard Sprayer on 2 iron spoke wheels. I've not seen any other sprayers like this .  I'm looking for someone that is knowledgable about this antique.  Interested in having it appraised.   The large wooden vat is in good condition and possibly good for restoration or museum. Please call 870-588-7410 if you are familiar with this type of machinery.  Tanks
