So it looks in reality. It is from an east german MiG-21SPS-K, which is similar to a soviet MiG-21PFM with GP-9 gunpod.
On the left site of the panel you have a dial switch (hope this is the correct english term). It is for weapon selection. Left position is for GP-9 gunpod, second to left is for R-3S missile, next is for S-5 rockets in UB-16 pods, right position is for bombs. The buttons 1, 2 and 3 i can only guess. Maybe it is the selection of the weapon station.
EDIT:
Correction. I was able to identify the word on top of the panel. It is ПЕРЕЗАРЯДКА, which means reloading. The GSha-23 had 3 so called Pyropatronen (pyrocartidges (?)). When the gun was jammed, the pilot pressed the button and the pyrocartidge was activated. The not working ammocartidge was moved out of the gun mechanism and the gun was ready for firing again.
