I am not sure what brand it is..
As I recall Carl's (TSR) v-body were double dump design and that v-body is a single dump.
Looks like an OEM style gasket in it. Many after market PG v-body do not use any gaskets.
Some people are like Slinkies... Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs.
