RARE Leslie Speaker Model 900U - $2,000 (Roseville)

I have a Leslie Speaker Model 900U Organ setup for sale.
I tried to search this online thru Google pictures and web but couldn't find one.
The 900 series and this one are way different in my side by side pic.
Solid wood cabinets top and bottom with no wheels.
Earlier design for sure compared to the 900s.
From what I was told is this is possibly a tube amp but I have not opened it or tried to test it.
