Very Rare Ozarka Model 89 vintage tube radio – AC Power
This radio was made in 1927 or 1928 as far as I can tell, I have tested all but 1 of the tubes on my Hickok tester, the test results are below.

Overall the radio is in good+ condition or a solid B+ for an unrestored example of a radio of this vintage; the chassis has some minor rust and paint flaking, cabinet will clean up nicely and it will shine with some auto wax, the bottom edge in the back has some minor rust. The bronze cast Ozarka name plate is in very very good condition. it has what I can tell to be an original power cord it is flexible and in fairly good condition.
I have not tested this unit since I do not have a suitable speaker, I have cleaned it up a bit and removed some of the dust and grime form the past 80 or so years. it is 100% unrestored, and complete. IT DOES NOT COME WITH A SPEAKER

Close up of the front of the cabinet after some minor cleaning. (note: this is with the chassis removed)
Back together on the mantle
underside bottom of the radio chassis
top view of chassis in cabinate – (I will remove all the tubes and pack it well in a double box)
Rear corner showin some rust, also there is some very small white paint speckles on the bottom edge, (0ver spray) the round hole is where the power cord comes out
the worst of the rust on the bottom edge (I would repaint the bottom edge since the top is clean and shines nicely)
the underside showing some slight surface rust again this is very slight, and looks better in person
bottom edge showing the rust
chassis removed from cabinate minor rust and flaking of the paint = it would shine up nicely if it were disassembled
inside of the cabinate showing the bottom plate and paper insulator both in excellant condition
