It also says something for an export Pr.11541 variant, is there any info for that?
That's the "Korsar" I jokingly mentioned earlier, even though second-of-class Yaroslav Mudriy is sometimes also referred to as Pr.1154.1.
Though I would wait on Golly's take on the subject, he export versions are probably not well-documented enough to be covered seriously. I can't remember seeing two pictures of the same Korsar design, or any going beyond flyers and models at military salons.
