Yep.. The Akkura and Polair kits are reboxed PZW Siedlce old one. Still having the oldest one made by Spółdzielnia "Wielobranżowa" in my drawer.
Your model looks no bad. I like these colours you used.
PS. There wasa release of the kit moulded with styrene containing some of teflon as memo serves. There was no way to paint it. Just there was no coat that cold stick that surface.
Got the propeller fitted at last. It's not totally straight but not bad for chopped up lengthened broken fixed and then dropped on the brown carpet and only found after a frantic half hour on my knees.
