MiG-23 early modifications had insufficient maneuverability. MiG-23ML and later one of the best fighters in its class

The quote from the Polish book is not mine, the name of this book is unknown to me

no worries
so are you quoting the production figures of
1300 mig-23M
1100 mig-23MLA
300 mig-23P
750 mig-23ML
directly from the red banner factory statistics

i was wondering as Airforces weekly say that MLA and ML were not different production and BOTH togather were under 1000

but Military balance in 1983 mention 2,100 fighter version mig-23M/ML/P/MLA in service with PVO + VVS

which one do you think is more accurate ? military balance ?
