Irwin,
Its all in training them correctly

About a dozen years ago I went to an estate sale and brought home a full pickup truck of damaged clocks that I paid 6oo dollars for. The wife ranted an raved that I had paid 6oo hard earned dollars for what she referred to as sticks!
I thought about my misdeeds very hard overnight and went back the next day with a 28 foot rider rental and filled it up with the rest of the estates clocks . When the wife found out the second trip cost $10000, she was literally speechless and has never said a word against my clock purchases since.
Truthfully, before that I was a watch collector and those two days were the first clock purchases I had ever made. I had no idea what I had bought, just figured that they were cheap enough by the pound to be ok.
The members of chapter 52 had a ball with that pile

They helped me match up movements to cases, Id'd the stuff for me and over the course of a few months bought enough stuff at about 10 cents on the dollar according to the guides that I about doubled my investment and ended up with a half dozen keepers.
happy hunting,
