Greetings. I recently purchased a used Getzen Eterna 1047FR and I'm trying to figure out how old it is. The only number that I can find on it I on the bell which says 1047FR-14XX (the "X" are other numbers). Is the 14XX the serial number? If so I've looked at some of previous posts on Getzen serial numbers (https://trombonechat.com/viewtopic.php?t=20799) as well the the horn-o-copia page list (https://www.horn-u-copia.net/serial/getzenlist.html) but I still can't figure it out. Most of these pages reference a "series" or letters at the beginning of the serial number. Again, mine doesn't have any letters. The only other number on the horn is a "K 16" stamped on the slide.

Can anyone help me make sense of this?

Thank you.

That 14XX is the serial. The K19 is just to keep the slide together. The inner and outer will have that stamped on it.

FYI. Case closed. I emailed Getzen customer service the serial number and they responded within an hour that it was from the late 2000s. Great customer service!
