Yes, the Dayton is a work of art. It's all brass (actually plated I think) with The fluid contained in the bottom resevoir. A large threaded plug opens in order to fill it up. Just like the lubesters, the flow back tube swings out of the way to fill your lighter. You push the little plunger on top to dispense the fluid. I stole this one on ebay a few months ago for $85. Prior to that, the last one I saw was priced at $850. The Shell pump is one of my favorites. That one I also got on ebay, and was thrilled to finally find one for sale. As I recall, it cost about $900. There is one of these on the cover of a petro collectable book. I think it's one of the one's that was authored by Mitch Stenzler.
