Well, once again "wasting" hours on the computer scanning eBay worked out in my favor. I decided I "needed" one more first model Ideal lubricating pump, if nothing else to establish a set of spare parts. I stumbled across an offering with both the wrench and clamp that looked otherwise complete as well (no sizing die or top punch.) I go it for the opening bid, and with shipping and taxes it was at my door for about $65. When it arrived, it was clean of grease and complete, with a nice amount of paint left! It's nicer than one or more of the ones I already had and I'm conflicted as to whether to use it or put into a museum display.
Anyway, other than one of the little cast iron spider-looking top piece to keep the rod/screw centered they are all four complete... and I believe that top piece is just lost somewhere on the top of my workbench in all the clutter. I really didn't set out to corner the market on these things, but sometimes you just get the chance and have to jump. Funny thing is, I was at home sick and about all I had the energy to do was surf the web on my laptop!
