Everything i can i will share..Dont worry i did not forget you..i need to find data for you about producer of colours wich were used on new serbian low vise MiG-29 sheme too.

I`m sorry bro to mess up your beautiful first name , we celebrate Svetozar nameday on may 16. , just four days before my birthday 🙂

Now, it seems you agree with E.Gordon that Iraqi Migs-21 were BIS even though at the beginning you have written the Iraqi Mig-21 aircraft passport says, it is a SM?

Is it true or not?

Yes but have you seen that i said that data about air intake size came from one mechanican..and yes i thought that this was hi trusted source.Please wait next week i will send someboody in base to to make some measurment job:)
So plese wait next week and we will certanly know what is right size of that intake.
P.S. I lied about my birthday:)) I did not know that this is imortant data here so i entered any date..is it important?:D( i dont like to give such kind of data..my birthay,my home adress etc..i gave my full name that is enogh:) I am not the only one who wrote this about that passport..see what other people say about same tihng on ABG forum(link posted by TEEJ)

I have a theory but you wont like it. 🙂 Those Iraqi Migs-21 in Yugoslavia were partly worn-out SM models from Soviet regiments, then overhauled, modified and then sold to Iraq. How typical for that times and Soviets dealing with non-trustworthy Arab countries

It is impossible that these are SMs .It is clear that it has larger bis hump..So it can be only ST or Bis..according some photos of air intake it looks like a BIS to me..but also some internal equipment sugest that it is older type.So it can be downgraded BIS or ST(if air intake is really smaller). I cant be SM,MF or real SMT.At tihs moment i belive more that this is bis..
