Hot Rods Mystery Early Sprint Car Steering Box

Wondering if someone can ID the manufacturer of this racing steering box, and the time-frame of when was available on the market. The alloy casting is 18" long and the 6" long center to center pitman arm is attached with a taper and a key. It is not a Franklin box. Thanks for any help.

 

Attention @Robert J. Palmer can you help him out?

 

I have seen them before, but I can't name the manufacturer. It's an early one pre war.

Franklin's were used frequently. I don't know if this is one.

 

Thanks for your post, no its not a franklin box, its for a Model T Ford racing car.
