Roller lube pump

I saw a post on a BB a while back and I am quite sure it was this one about somebody haveing these pumps for sale. He was rebuilding them and selling them. I have used every search term I can think of and can't find that post.
I let it slip that I have one I might sell and now I am swamped with people wanting to buy it. Can any body give a clue what it might be worth or bring up the post I mentioned.
Thanks in advance for your help.

MK, try Kelly on the ACME board. He is the ultimate volume pump guru for pumps used to lube rollers.
