Hello Kody! In order to get a manufacture year, we usually look at the serial number. It can either be on the bell with the engraving or on the valve section (usually the 2nd valve). If you would like to, please send pictures of the full front, full back, close up of engraving, and close up of the valve section that shows the serial number (if available). These images can also help determine the manufacture year. Send these images in an email to vsimonetti@nc.rr.com and you should get an email reply soon after! Thank you!

Hello. I have recently purchased a Kalashen Tuba with the serial number 1940. Can you please help me guess as to the manufacture year?
Thank you
