Excellent book
Sorry can’t help you. This site gots lots of Su-22 pics, but I didn’t notice any white markings: http://www.lotnictwo.net/galselect.php?p=0&ui=133&mi=52&quer=1=1&ti=134&selectby=fotoID%20DESC
But I would love to hear your opinion on the book, please?
Very much worth the price.
It’s the best single source I know of for all Su-7 variants and descendants. Many detail photos, development and combat history, profiles and drawings. One part I especially liked was the analysis of Soviet photos of the swing-wing demonstrator’s first airshow appearance–how the flashy Sukhoi markings were airbrushed out of the photos to make it seem like the aircraft was a service machine rather than a prototype.
