Question Can you help me ID these tanks?

[JohnN]

This is a vintage set of triples I picked up.

Steel,
23" x 5.5."
Common manifold with "J" valve

I found a chart that says 45 ft^3 each, so 135 ft^3 for the set

What are the stampings?

Walter Kidde is the manufacturer, I believe they are nominal capacity of 44cf but @Luis H would be able to verify

Way cool. I found this chart that puts the tanks at 45 cf. We're within spitting range of each other on capacity.

At 2100 psi, that gives me about 110 cf of gas. What could possibly go wrong. . .
