I recommend the panel designed by Thomas Ferber:
FS98 JU-52/3m Photoreal panel & instruments.
The photorealistic panel of one of the most
successful planes of the 30's and 40's.
Panel and Instruments in the style of the
Early 40's. New Old-style Instruments by HGHB.

I've left the bitmap here as a preview.
It is VERY authentic, especially with the
Askania remote compass by Arne Bartels.
