I just had to share this. A very good trumpet player friend of mine came for a holiday visit today. We were futzin' around with C trumpets and mouthpieces, etc. We both primarily play Bach 229/25A configurations, but there were also two Yamahas and a Bach 239/25H in the mix. We were looking at the serial numbers just out of curiousity and found out the Bach Cs were IDENTICAL up to the last number, with the last being a 2 on his and a 9 on mine.....only 7 apart on the assembly line. When he was reading off his serial number and I was looking at mine, I felt like I was reading a lottery ticket. LOL. We didn't buy these horns at the same time or at the same place. We were amazed at the odds and the irony. Cool, huh?
