I was at McCormick-Stillman Railroad Park in Scottsdale last weekend (an AMAZING place if you like trains) and saw a guy wearing one that looked pretty much exactly like this. I commented on it - he had no idea what model it was, or anything about it. He bought it when he was 19 years old and had been wearing it ever since. I told him it was fairly valuable, so don't just give it away at some point.
