Wanting to know the age of my tuba

Tracing a Yamaha serial number is tricky, as they weren't terribly consistent about it. That serial number could match a guitar made

30th Nov 1979 at the Kaohsiung Factory Taiwan, or
30th Nov 1999 at the YMMI Indonesia factory

If you know the approximate age you may be able to sort that.

Can you forward some photos to me? Serial numbers and Kay guitars vary by the age of the instrument. Also can you take a photo of any label inside the sound hole or at least tell me what it says in there, where was it made, etc. I'll await your response.

maybe $200 and shipping it to Kenya Check online.

If your piano was made for the U.S. and is a grand or upright, this serial number would show that this piano came from the mid 70's 1973-77 and was manufactured in Hamamatsu, Japan. You should be able to google your piano from here to find others similar to it to get a price or call your local piano tuner!

Serial numbers used to be used to tell the age of instruments. It seems now with Yamaha they are used as a tracking number for accounts purposes.

Here are some links:http://www.yamaha.com/apps/guitararchives/serialnumberwizard.asp Also:https://store.bluebookinc.com/Info/PDF/EGuitar/ElectricSerialization.pdf (scroll to the bottom) Also have a look at this forum:http://www.mylespaul.com/forums/other-les-pauls/21393-yamaha-studio-lord.html You didn't mention the model number which should be on the headstock plate that covers the truss rod adjuster. My guess is late 70s to early 1980.
