!960's Latham Dual Axial flow super charger

[bodypainter64]

My brother passed away a few years ago, and we were cleaning out his garage.
In there is a Latham Dual axial flow super charger with four Weber single barrel side draft carbs. I do remember seeing it on a SBC powered '29 chevy pickup.
I did some research and found out there were about 600 of these types made.
Wondering what it might be worth. I did see one on a vehicle on Barret Jackson and they said the owner paid $6000 since it is such a rare item. Any help would be greatly appreciated.

I see them selling from 1800 to about 3500 depending on how nice and complete they are. The Webers wouldn't be stock, they came with carter sidedrafts.. Manifolds are worth several hundred for the common ones Drive pulleys and tensioners are usually missing and can bring some bucks. While they look neat, they are really not the answer to supercharging. Poor throttle response, short belt life. There is a Latham thread over on the HAMB that would like a pic of what you have.
