The serial number is more likely 411908. There have been reports on other forums of the S-33s having seemingly nonsensical S/Ns for when they were made. Most likely the 1 at the beginning was a mistake or a worn 4 stamp. These horns were produced around the time that Selmer USA bought out Buescher.

I had one of these horns a few years ago and greatly regret selling it. I really liked the horn. It was easy to play and was very sturdily built.

Unfortunately, since it's not a model 140 or earlier Aristocrat, the market for these is limited and they usually are considered student horns. Therefore, they're not worth a whole lot. At full retail, I'd say under $600 in outstanding condition with a fresh repad. Everything's subjective
