I don't know if it will help, but they have a Facebook page at https://www.facebook.com/PolecatAerospace
You might try leaving a note there and see what comes back.
I did my L3 on a Polecat 10" Fat Man a little over a week ago. I never had to contact them, but the order shipped quickly. Great products and they're still around. Hopefully a phone call or post to their Facebook page will get a response.
I asked Mike G from Bay Area Rocketry about Polecat Aerospace yesterday at October Skies. Mike now as a boatload of Polecat kits. He said Tim was traveling which may explain the lack of comms.
