Looks just like my 87. Seller gives the plate number as 21244, bet they missed a number off. The later eighties script logo is a brighter gold than the first ones which are silvery, otherwise exactly the same.
Yes you are right. I think the bright gold logo must've started when they changed to 'quality instruments of the world'. £250 is a good price, I'd have it if it were closer and I'm not a lefty!
Just on the different colour logos, I note my 83 logo decal is not one piece like all the other later ones I've seen. Just came across this thread where it's noted that the 83 script goldstar fanatic decals were 3 piece, then they went into one piece. Maybe it's just the one piece decals that have silvery logo. deffo not many about.
