Nice. I had a chance to get red-white MIJ '86 strat with Floyd in HSS configuration, mint condition, 300 euros. I arranged for the trade, and just announced it to my friend on IRC. He just said "hmm", and started asking all kinds of specific questions about the guitar, last being serial no. I sent him all hi-res pictures that trader sent me, and then he confirmed that guitar was stolen two days prior to that discussion. He pointed me to a thread on local musicians forum, and it was indeed the same Stratocaster.
I actually had second thoughts about getting it, knowing that the owner reported theft to police a day prior, and they need at least two-three days more to spread the word to postal services, couriers and stuff (due to oversized bureaucracy). So i could receieve it, pay a 100 more euros for repaint, and chances of getting me would be down to 0.01%.
My morale parallel went to - look, if i ain't purchasing it, someone else will. It was really hard, with our incompetent police, for owner to get back his stolen item (and indeed, he didn't to this day, and that was 10 months ago). However, i didn't, because that guy was the first owner of that guitar. It was his guitar for 20+ years. Mint condition. If someone did that to me, i'd kill him. Therefore, i ain't doing it either. I haven't regreted that decision, and i think i did the right thing.
On the other hand, i couldn't turn in the stealer, because of a very complex situation. So i just bailed out of the whole story.
