I recently caught N135EM, a private L-39.
Just last year the aircraft was uploaded as a L-39C, yet L-39ZA was displayed on the aircraft and the registration shows L-39ZA.
Currently it is the opposite. Now it has been repainted, still on the same certificate as before, but it now displays L-39C on the aircraft. The registration still says it's a ZA.

For this aircraft in particular and for future reference in general, should I stick with what it auto-fills as(L-39C), or should I put the model it is registered as(L-39ZA) and maybe add a comment to screener explaining the situation?
