You could make 2 versions if you really wanted
2007 → pre production series Mig35 with early radar - AE
2021 → Production series Mig35(s - serial***) with - AME
Serial as in whole 6 ahh frames and 6 prototypes… (also some shady stuff about supposedly being developed carrier adapter Mig35 but they are all from 2019 and surely nothing came out of it)
