I think the decal is legit but need the neck code like you say. Might have had a neck swap and the plate went with the neck, though plates tend to stay with the bodies. If the plate is correct, why swap a standard tokai RW neck for another? Could be for the logo I suppose.Very odd...
The serial number fits with other early 1983 guitars I believe. Possibly late 1982.
But a June stamp.
And spag logo. Do you guys think that decal is legit?
Without a neck code I would lean towards partscaster.
