Here is a Big cutting torch that appears to have never been used. It's made by Airco and is a style number 4335. It looks nearly identical to Concoa 9000 series at this link:
The length from the tip to the handle is 21 inches, and the overall length is 30inches.
It has a 75 degree head and the oxygen orifice is 1/4 inch dia however, the tip can be changed to a smaller one. The best information I can find indicates this torch can cut steel thicknesses up to 12 inches!!
It seems that Airco was bought out by Concoa and information that I have found on the internet indicates that Concoa still manufacturers parts & accessories for this torch.
