He is happy about it Papaw.
This is a nice old torch, if you guys see a nice torch, looks for these things.
It's a flat tank but these points refer to all shape torches. You will notice the hook on the burner is cast with the burner (not a threaded screw in hook)
The top and bottom of the tank are cast and the copper middle is soldered to these. Newer models where pressed. Often the soldering looks quite armature or messy, that's how they were turned out, it's not a repair.
The priming pump is in the handle rather than the tank.
Pick it up, it will be quite heavy if it's an older model.
