Peter,
Duane B, has done considerable research on these 20's supers.
There is more than enough of Vinzer's super for a good restoration.
Like many 20's home made construction quality varies widely. During a restoration build quality can be upgraded with an eye toward authenticity.
A simple review shows two broken sockets and a missing jack, all relatively easy to find. Though the bus wiring is in shambles, mapping the circuit as best as possible then re-wiring will greatly improve performance (cold joints) and appearance. The radio can be operated from a socket power supply such as an ARBE-III, (I recommend) as a homemade supply will often not have the low impedance required and hum...
There may be enough left of the IF decals to reproduce or someone known as a super collector may be able to image an IF to create replica decals.
The radio may have provision for a loop, often this is a center-tapped loop.
A high impedance horn or cone speaker. The cone will take advantage of the "higher" fidelity of Karas transformers. Something the builder seems to have considered important.
What can be expected is the radio will have "two-spot" tuning from the use of independent tuning condensers and no provision for tracking.
