Cheers for the reply.

I searched “suzuki strat” in google and came up with a review from Harmony Central. This review states http://www.suzukimusic.co.uk/ as the manufacturer. I wrote to them and asked them if this gat was one of theirs and this was the reply:

“Not one of ours unfortunately. This is from the Suzuki Violin Company in Nagoya, Japan. Our manufacturer is Suzuki Corporation, Hamamatsu.”

So I’ve written to the Suzuki Violin company but no reply yet!

I also wrote to http://www.music-trade.co.jp to see if they could shed some light on it, and here’s what they said:

“Well, it is very difficult for me to evaluate this guitar.
First of all, it doesn’t look like 70’s Suzuki.
The design should be Late 80’s to early 90’s.
But, it should be export only model.
I’m guessing Korean made. Just use the Suzuki name.
I’m not sure when they were bankrupted.
It should be 80’s.”

I’ve now taken the whole guitar apart but not found a serial number or one shred of writing on it, other than on the headstock.

Good thing I love a good mystery!
