Unfortunately, your plan did not work for me! Not only that, I did a reverse haggling! So you might ask yourself what on earth is reverse haggling!
Well last Saturday while we had a snow storm going and temps were dropping like crazy one of my colleagues who lives about 60 miles from me, texted me a photo (see the first photo below) of a vise and stated that there is an estate sale for his mom as she is being moved to a nursing home. And that he has found his dad's (a machinist by trade who died 11 years ago) old vise in the shed! So, since he knew of my addiction he was wondering if I wanted before it goes on sale.
I called him right away and asked how much? He said are you sure? It is pretty rusted. I said regardless, I want it. He said how about
$20!

At this point I was conflicted, one half of me wanted to say yes but the little stupid thing called my conscience was nagging me. While we are not close friends, we are colleagues plus it was for his widowed mom. So I offered $100. I guess his conscience was bugging him too, so he kept saying well it is old and rusty, isn't that too much. I said this vise is a lot more valuable than you think and I am very happy with my offer. So we agreed on $100 (
reverse haggling by both sides 
).
Because of damn snow and extreme cold I worked from home the whole week until today (my work place is about 60 mile away). But he lives very close to work so last Monday he had brought the vise to work and left it in my office (he had security unlock my office).
Today finally I made it work and this ruggedly handsome 400s was waiting for me. I went to his office to pay him and he was still insisting may be we should knock down the price but I gave him the $100 as we had agreed on, and could not be happier.
With the exceptions of a bit of surface rust, the vise is in mint condition. Nothing include dynamic jaw, swivel locks etc is seized. The jaw inserts are mint condition and there are no cuts, dents and bruises

. The date stamp is Jan 1971.
I have a feeling this fella is heading for a great treatment (
bead blasting, nickle plating and then powder coating and baking) soon. Four of of my current vises have gone through the same treatment already. A shop King, a 3" bullet, a Parker 955 and a Prentiss 524. You can see the photos of them in my photo album (under my profile).
