I guwno wielke happens... I have some weird downloading problems with your files - it's always broken... Could you pls post it as separate pictures in the attachemnets? Dzienkuje!
I've tried to make a rar file but the uploading was unsuccessful.I don't know why.
I'll try to send it in another way.Let me know if you get it via e-mail.
Yeap,The Yak-23 looks like a wast stuff.No wonder it is a forgotten fighter and not popular as Sabre is,for instance.Therefore there is a problem to find any info on it.I've had the TBU publication so far and it was the only one.I hope it was useful for you really.I'll be waiting for your pics of the model.
