I had the opposite problem yesterday.

A craigslist ad for a '50s vintage raleigh went up the other evening. I emailed the seller very soon after the ad went up and said I would like to look at the bike.

He emailed me back said I was welcome to come look at it, but he couldn't sell it to me, as another seller was driving from Wisconsin to look at it on Saturday. If that gentleman didn't buy it, he would let me know. I went to look at it, and the bike does appear to be from the '50s--56 8 on the hub, old dynohub and light, Brooks saddle. He said he'd keep me posted, and I thanked him for his time.

Nice to meet people with integrity.
