Hot Rods Zenith carb I.D. - Might be industrial

Digging through a box of Chevy stuff I just bought at an auction, I came across what looks like a new Zenith side draft. I chased what info is on it through the Internet and get hints it is industrial.. Any way, I suspect someone could use it. Any ideas? The plastic on the fittingoff the throat bowl makes it look a little modern.

There is a tag on it with the following numbers

9 00
014131
LZ 77 L

 

Google,,,,,,,,,,,similar shown for Wisconsin's
C&L Tractor parts

 

^^ yup, electric fuel shut off valve is modern.
although still very similar in construction and parts used to the up draft zenith found on my 67 farmall but without the plastic and electric gizmos

 

I have a friend that is looking for a carb like that. His name is Tommy 214-504-5574. Please give him a call if you want to sell it.
