I just purchased a Yamaha G1. On the harp, in the correct place, it has G1 embossed with the serial number R 4636912.

I did some research on Yamaha's web site. in 1988, the serial number ranges are 449xxxx-456xxxx. In 1989, the ranges are 467xxxx-467xxxx. My piano's serial number is 463xxxx which doesn't fall within the ranges on Yamaha's website. Should I believe that my piano was made in 1988 or 1989? Or is there something fishy about this?

And, their website doesn't address the "R" before the serial number. What does that mean?

thanks
Steve

According to http://www.yamaha.com/ussub/piano/serialnumberlookup.html your piano was made for the US market, so assuming you are in the US it is not gray market.

I believe the left column is for uprights, the right for grands, at least that's how I read it.

The "R" at the beginning of the serial # is likely that particular G1 model designation, which, though the actual G model did not change, some components or design may have from one G model to the next.

My 1978 Yamaha C7 has a B at the beginning of the serial #; DrewBone, another member here, has a slightely newer C7 (1979?) with a D at the beginning of the serial #. Notice the pattern?

Of course, I could be wrong.

Hello- I have a Yamaha G2 that I bought almost exactly 1 year ago. I think it's a 1972 model. I'm not at home looking at my piano but my serial number was not found on the Yamaha website either since it's a gray market- so that's normal. FWIW- It's been an incredibly stable piano. There was a short period of time in the fall when the humidity changed frequently and the piano sounded awful but by the time the tech came it had "re-adjusted" itself to the point where the tech decided just to regulate the piano instead and he did a very rough tuning adjustment since it was basically in tune. We have been extremely happy with our piano.

In regards to at least the Yamaha "C" series, I do believe that your summation is regards to the incremental "letter" models and their associated incremental serial numbers is correct Mr. Rick.

My C7 model "D", just like the previous models "B" and "C" has a letter preceding the serial number, i.e., thusly, here's mine (yes it was built in 1979):

Below is Yamaha's own (partial, sorry I couldn't shrink the original webpage any farther to include the entire list in the image, though I will include the link below) serial number list, which unfortunately doesn't convey when the particular "letter" models were introduced, though I suppose that information is out there somewhere:

I once wondered how legit was the serial number on a gray market piano. It does not seem difficult to scrape off the original and put on a serial number to make a piano appear "newer". I searched and found these postings on a British forum:
http://www.piano-tuners.org/piano-forums/viewtopic.php?f=3&t=3709
So apparently, there are pianos with a funky serial number out there.

Yamaha's list is confusing. Did they run parallel sets of serial numbers from 1972-1999 in the chart above. Meaning it is possible to have an upright and grand with identical numbers. Or are they just showing the first number used for a grand/upright in that year?

To the original poster, looking at the right column for Hamamatsu. Your piano would be made in 1988.

It is possible to remove the painted letters in the serial # on the cast iron plate and paint new/different numbers. However, the real serial # is also located in different places on the piano; i.e. the action assembly.

Of course, a savvy counterfeiter could do a through job of altering all the serial numbers, which is a crime; it's called fraud (if it can be proven).

Andy, I think the primary difference between the "B" and the "D" model C7 is the fact that Yamaha made a big change in the design of the tail section of the piano. The tail section of my C7 is not a smooth circular curve, but an odd off-set curve, if that makes any sense.

The left side of the tail curve is longer than the right side, making the tail curve asymmetrical. Does that make any sense?

Also, my C7 "B" is 7'4"; I think your "D" is the 7'6" model, another difference between the two models (likely related to the tail curve design change).

Anyway, that is at least a couple of the design changes between the B and D versions of the C7 (I think smile ). If I'm wrong, maybe some of the pros will chime in and correct me.
