Ed, I have a set of Masai windows, clear. Never used them. There's one flaw with the set. On one side, the slide lock was stuck. I squeezed it a tad bit too hard and 'bent' the plastic - not broken yet, but I'd be gentle with it. The lock operates now.
I boxed them back up and they are sitting in my garage attic.
I'm making a stop in Fredricksburg, VA in Dec so I can bring them down there. I'll have to check with the guy that I'm making a stop for to see if we can use his garage as a drop point.
Make me an offer.
