Bob will appreciate this story. Shoot, he may even remember it.
The reason I even bring it up goes along with what Suzanne is doing except she's doing her homework and is far more prepared than most neophytes.
There was a friend of ours, an avid O Scale modeler of some note, a Pearl Harbor survivor, a decorated WWII Marine (got out in '45 or '46 as a 1st Sgt, tough as nails, with a heart of gold...unless you got on his wrong side. One of the most honest and honorable people I've ever known. He lived in Southern California and was known far & wide. Many times, as O Scale items were brought into local hobby shops/model train stores in the area, he would be called. One time he received such a call from a well known shop in Pasadena and it turns out a widow was trying to sell her late husband's collection. Si examined the collection and asked the lady what she wanted for it. She stated her price and Si said, it's worth more than that a gave her twice as much as she wanted. That's how it's done!
There was another time where a modeler took advantage, in a similar situation. Si found out about it and eviscerated the guy. From that day forward Si would have nothing to do with him. Oh yeah, once you were on the bad list, heaven help you.
One of my heroes.
