Welding/trying to identify a cutting torch


cutting torch
cutting torch  
I bought this cutting torch in a box of things at an auction but I can't find any identifying information about it. Someone told me it was a Smith but I'm not sure. Can you give me any info??? I've attached a picture and it is the top item. THANK YOU in advance for all your help.

Looks like an Airco torch to me.
Airco doesn't exist anymore, but Concoa and Koike both have the rights to make Airco type torches.

Concoa makes a reproduction of that torch called the Model 9700.
I bought one last year and love it.

Airco style torches are Tip-Mixed torches so it is impossible to back-fire them into the torch handle.

The tips are available at most welding supply stores as "Airco" style.

The tips should look like this

I would have it checked out by a repair shop before using.
Old torches can have dangerous leaks in the valves.
