I'm building a new (period) garage for my newly acquired 72' Corvette and looking for a working Eco Tireflator to actually use on my vehicles. Interested in the model(s) with the brass/metal crank rather than the plastic knob models. Looking at the custom order refurbished models available on eBay for comparison but hoping to get something at least as good, or better from a forum member. I live in Jacksonville Florida.
