Help needed with identifying a Jazz Sound

[Stan W]

I have bought this jazz sound: http://www.ebay.com/itm/RARE-Tokai-Jazz-Sound-circa-78-Vintage-1-WEEK-SPECIAL-SALE-/281746311310?pt=LH_DefaultDomain_3&hash=item419963888e&nma=true&si=s9zPREr8vDnAmMIh5xgF6efzBPo%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557

And here are some photos I've made

As we can see, on the neck is writen kind of 12=3
And under the electronic plate we can see 12=3MR
The serial number is made of 7 digits: 1023843

Anyone can tell me, what age and what kind of jazz sound is it?
ofc. sorry for my english.
Cheers!

Hi Stan,

From what I've seen and read, the description is quite accurate - Alder body, 34" scale, dark rosewood fingerboard, etc.
From the codes I can tell you that the neck and body are a matched set - they have not been swapped and they were made prior to 1985.
MR is the colour code (Metallic Red) and the numbers indicate a December build. As the serial number is from very late 1981, then that would be it's Age - 34years old

regards
Peter Mac
