I believe by the description It's a Wayne 615 pump, though he claims its an 87B which i think he cant read through the rattle can paint properly. the seller peered through a small door and found a cylinder type device near the bottom. I'm assuming this would be the original pump mechanism, though there is no handle. I have no pix yet. Long drive, holiday, girlfriend complaint about me spending a bunch of money on something she doesn't "get". I just have to tell her "man cave" and she won't complain anymore! Anyway, I'm going to just go get this based upon my discovery of you all and the Comunity. I believe that the poor 20 year old rattle can paint can be removed and reveal the original paint scheme, etc. looks like I'm beginning a journey into petroliana! Who knew???
