Hi Pieter,
I agree with Yammer. Probably not all Fulcrums were active with the Moldovan Air Force. Please note this pic (

Add to this that at least nowadays the MiG-29 that stayed behind in Markuleshti weir yellow codes on the air intake. So most likely they flew white and yellow borts together all the time since independence.
The last fact I would like to point out is that the USAF most likely never registrated the color of the bort code. I have received the full list of construction numbers directly from USAF air intel department (!) and they gave all construction numbers and bort numbers, but no colors.
Good luck,
Joost
