TOPIC: Any info on Glassmaster boats?

I decided to let my '58 Lonestar Holiday go, and just put a deposit on a '60 Glassmaster runabout. I can't wait to pick it up next weekend. It's ready for the water, vs. the Lonestar, which would probably take another summer or two.
Does anyone have any info or pictures of these boats? I found a '64 on a classifieds site, but that's the earliest. I'm curious to see if the swivel seats up front are original. Don't remember seeing that before in an early boat. Thanks for any help.

Until something else comes up, here's what seems to be an early Glassmaster that was posted on craigslist awhile back.
