Getting date information on lesser known instrument brands (Conn horns are one thing, guitars are another) can be difficult. in this case, Conn wouldn't have made the guitar, but would have sourced it from a offshore maker. I suspect it would be made by Samick. Generally, the first two numbers are the year on Samick products, so probably 1979.

Unfortunatly, once you get past the well known Fender/Gibson/Gretch brands, info gets harder to come by.o can try contacting Eko directly in Italy. Here's a link

Or you can date the guitar off the codes on the pots. Here's some info on that-

This guitar is from the U.S. Vintage Series
made at the Corona Plant (Fender), USA
in the Year(s): Cannot be determined from serial number,
however you can consult this chart showing the
corelation between serial numbers and dates found on the neck
Fender MIA RI Serial Number vs. Neck Date (Note the earliest I'm seeing is mid 80s)

It would help if you had identified the guitar maker and location of the serial number. I assume it's a Yamaha, but the serial number doesn't coincide with any of the typical systems they used. The first two numbers could be the year of manufacture, but the earliest Yamaha I could find was 1966, so you may want to go direct to Yamaha and ask if they recognize the number based on the model number.Yamaha Corporation of America

Aria gutar model A 586 seria 66 hau ilde is it

According to yamaha's site, that's an invalid serial number??!!??

I would guess that might be the date code.

Other sites report 5, 6 and 8 "digit only" serial numbers.

Nothing for 7 numbers.

If i had to guess, the earliest...1971
Hope this helps.
