That's a fine model you present us here, Emre! Congrats for winning the MoM-prize. Yes, PRU-Blue is hard to get, I noticed that, too. But Agama (Czech Rep.) and Xtracrylix have it in their program (Agama sells it as Azure Blue

but it's too dark for that.
I have here also a Hasegawa Sabre in my stash, but a different one. It's the famous "JA-111" from JG 71 "Richthofen", flown by no one less than Major Erich Hartmann during his time as CO of that German Air Force Wing. Have to get that kit out of the pile .....
Happy modelling!
