Quote Reply Topic: Sigma Serial Number. Posted: 04 September 2012 at 09:04. Hi, Is there any way to find out how old is your Sigma lens using the serial number? I haven't found any database on-line where you can look up a lens after the sn provided. Sigma's made in Japan from 1970 through 1979 used a paper label to identify the model and serial number of the instrument. The earliest examples had a plain black on white inner paper label giving the model and serial numbers. Later one's (c1972 onward) had white labels that had gold lettering with a border, often reddish-brown or purple in color. Got a sigma dm2 i've had for years but needs some work. A guy at a music shop said some of those sigmas could be worth a few hundred bucks. I'd like to have an idea on it before i try to fix it myself.the serial number is 87110807 on the paper tag in soundhole that also says c.f. It has the sigma guitars est.1970 logo on the headstock.any info would be appreciated. I'M A DEALER AND NEED MORE INFORMATION ON HOW THE NEW CITES REGULATIONS WILL.

Some of these guitars still had the early peghead logo, instead of the 'Second Generation Sigma' Martin style logo that started in approximately 1976.

Sigma DR-35
Sigma DR-35, Made in Japan 1980
I finally managed to find another Japan made Sigma, this time a 1980 Sigma DR-35. It’s a beautiful looking Martin D-35 copy with a 3-piece rosewood back. They are pretty hard to come by these early 1980’s Japan made Sigma’s and sometimes very expensive too, between 500-1500€ depending on the model. I didn’t buy this for myself, I’m way too happy with my Sigma DR-41 at the moment and on top of that I’m actually trying to thin out my Japanese guitar collection. I got it for my friend Wolf who just like me have gone from a pretty solid Gibson obsession to realise that perhaps that Martin sound is not that bad after all. There is something of that punchy mids and clear ringing highs in the Martin sound that these Japanese made Sigma’s have too, after all they were commissioned by C. F. Martin & Co. I thought my Sigma DR-41 was loud and had a very punchy midrange but this Sigma is one step beyond, I guess because of the 3-piece back. I like the highs and the overtones better in mine but still, this is an amazing sounding guitar that I thought long and hard about keeping for myself. I was sure that my Sigma DR-41 was made in 1982 since the serial number starts with E82 but since this Sigma DR-35’s serial number also starts with E82 and came with a receipt that proves that it was sold in September 1980 it must have been made that year, or earlier.
This guitar had apparently been in storage for the last 30 years, since the original owner died and that seems plausible, it’s in really good shape for it’s age.
The classic Made in Japan football stamp, burnt in to the back brace that was used from 1978-1983 on Japan made Sigma’s stating: Sigma Guitars – Made in Japan for – C.F. Martin & Co, just like on mySigma DR-41. The rosewood looks really nice on this Sigma, even better than on mine.

Wolf asked me to install a LR Baggs iBeam in the Sigma before he received it and since I recently installed the LR Baggs Lyrics in my Sigma DR-41 it was a pretty easy task. We actually got to try them both out last Saturday when we played live with Cherry & Wolf at La Sonora, it sounded something like this. I did two tests to make it easier to compare the Sigma DR-35 with the iBeam to the Sigma DR-41 with the Lyrics. They both sounds pretty darn great, but in different ways.

The original receipt from 26 September 1980. The guitar cost 475 Deutsche Mark which would be around 245€ today and probably a lot more 36 years ago. Taken from my Instagram
