Help identifying aircraft type

[Tommaso Dal Maso]

Hello guys, in a recent trip to Bulgaria I found these two MiGs sitting in a field of a museum. They are completely unmarked and so (I believe) impossible to identify registration-wise (and serial). I am curious however about what aircraft type they might be as I'm not excessively instructed on soviet russian aviation, and also to maybe upload them on the db in the future. Any help is appreciated, thank you -Tommaso

Looks to me two Lim-5's. A location would help

Krumovo air base // Plovdiv Airport, Bulgaria. Here there are aircrafts from all former air bases of the country so doubt it can be of greater help. Thank you however

They are both Bulgaria Air Force ex Mig-15bis

At least one is already on JP :

Thanks Alex, hadn't seen it despite going through the photos in the db of the location. Will search more info for the second one
