i've bought a MAT recently myself, if you turn the guitar around and open the back you'll find the serial number there. Also on the tokai registry there is a magazine that is (very helpfully) scanned in, your guitar is probably made around 1985. How much did you pay?
Just bought a tokai MAT, bought for ?179.99. The 1986 catalogue says it's a CM802. Hasn't got tremolo. Any feedback? Is it a good price? Let me know what your opinion on this model.
