Just as the title says, has anyone heard of INPACO? A friend has some spark plugs for sale and this is a brand that I have never heard of and can find next to nothing on-line. All I can find are some old auction listings and some Ebay listings but not much else. I know there were a ton of different manufacturers out there but I can not find anything on this one. Has anyone come across them before or even run them. They are "supposedly" 1/2" pipe thread and N.O.S., when I get some photos I will post them. If the pipe thread and N.O.S.turn out to be true, I figure I am safe at his asking price but would just like some information if anyone has any.

Just one of many different brands of aftermarket plugs made in the 30s through 50s. Lots of them around and mostly of interest to collectors, although they are pretty common. The plugs shown are not Model T though.
