Westone Rainbow from 1981 is quite a beauty, which I guess is understandable seeing as it was their top of the range model at the time. Obviously it's inspired by the Gibson 335 semi-hollow body, and I'd guess that it'd have the same construction featuring the solid block through the middle of the body. This example also features a discrete flower design, which is said to be original to the guitar and not a later addition (the seller says it was a "review model").
This guitar is currently being offered for sale on eBay, and with less than eight hours to go as I type this it has garnered quite a lot of interest and bids already.
