Last I heard, Tim Ziegenbein (spelling?) in Oregon owned Polecat. Yes, it's basically a one-man/one family show, and not his/their day job.
I have the 10" FatMan. Awesome rocket. After attempting to lawn-dart the rocket, I was able to procure a replacement segment of 10" body-tube from the company early this year (March, maybe), but it took some doing (repeated calls and emails). At that time, they indicated they were having issues getting someone to glass the cardboard tubing that they used - their usual supplier stopped doing it.
I'm hoping that they've just closed the storefront until they can figure out their supply line issues and will be back (eventually), but I can't make any statements as to the accuracy of that hope. After the complaints I've heard/seen on this forum about non-responsive suppliers, I think that closing the storefront is likely the most responsible action if inventory is unavailable.
YMMV
