Guess what this is...
I was going through all the misc parts I have collected and looking at some of the stuff my dad collected and found this.
My dad made it, I don't rember why. But I do know what it is.9
It is 22 inches long, 20 1/2 to the hose clamp about 3/16 diameter. It has 2 wires coming out of one end and the other is soldered closed. It is made from soft copper tubing.
Hint it has a purpose associated with a 273 but not exclusively.
WHAT IS IT?
GOOD LUCK
