Lots of of fingerprints and grime and dirt. I'd be shocked if this has ever been cleaned. Pre-serial number. We love patina so we're not cleaning this. It's been drilled for eight rivets but we liked the sound of four, so that's what you're hearing in the clip. We'll include four extra rivets when you buy it! No flea bites or cracks. Just a solid, well-loved 602.
