Help with a convector

Skippy_2

I'm a small one man show up in the hills of Colorado and have been asked to fix a leak on a convector. It is 1/2 inch tubing and on the outside of the pipe it looks like the inside of a spiro vent. Where the leak is there seems to be threads but I'm not sure about that. I want to know what the brand of the convector is so that I could get a break down on it or something. Thanks for the help.

take it to a car radiator shop to be fixed & tested
