Kasper,
Oh, wow. Just, wow. I've seen photos of the gold colored square / tonneau cased one (the one featured in the Texas Instruments TV commercials), but I didn't even know that there was a round stainless variety. That's just gorgeous. I passed up an eBay auction years ago for a new-in-box gold one and wish I hadn't. Kudos. That's quite a score.
Here's a link to the 1978 TV commercial with the gold Starburst:
