Hey DRockMonolith,
I’ve got a couple of thoughts concerning your guitar.
First, a bit of background you may or may not know.
Morris is one of the trade names used by the Moridaira company. Moridaira is a OEM Manufacturer that began operations in Japan and then moved to Korea. They are known for producing entry and intermediate level electric and acoustic instruments although they no longer produce solid body guitars.
Looking at the photo supplied by GLW suggests to me your guitar is mid 80’s and built in Korea. Here’s what I’m thinking. To my knowledge, the first builder to produce this “star” shape was Charvel San Dimas in 1981. By 1983, Hondo had copied the shape and was producing their own star model. I have the 1983 Morris catalog posted on VintAxe so I took a look and there are no Morris star models pictured. They are still selling pretty conventional looking instruments.
So, my conclusion is that Morris began marketing their star shaped guitar after Hondo which I would guess would be around 1984-85.
Plenty of conjecture here, but it is my best guess. A look at the headstock would be very informative. sb
