Early flathead Hilborn Fuel Injection

I reciently bought a Hilborn-Travers early fuel injection unit, it has patent pending cast into the top, and the number 134 stamped at the bottom.
it also has Los Angles, California, cast below the name. It appeares to be complete, nice working condition. I found an article about Stuart Hilborn
in a Rodders Journal, and it mentioned Travers as an early partner.
I am trying to figure out if I paid to much for it, I really think its pretty rare. Anyone have any comment or ideas on the Value of these units.

 

Hilborn has all the information on when it was built and who bought it originally. From what little I know they started with # 100, I have serial # 137.

 

How much is too much? Not sure. What did you pay for it? Did you get the pump with it as well?

 

its worth what you paid for it no more no less, now put it on a car and go.......
