Hey Paul,

Here is a pic of an old Teapot vac kit that a friend of mine is selling on Ebay. It's not the King Cobra, but it will give you an idea of what the kits looked like.
I'll respond to the rest of your email later this week and post some pics here. There seems to be a bunch of thread lurkers interested too - pics might be useful to others as well.
BTW, I have not forgotten about the BRDC and Armstrong graphics. Still chewing on those and too many other projects. But I am planning on sending them to print at the end of the summer.
Steve
