James, wonderful looking Sabres! I plan to do a few of the early ones as well. I'll be PM'ing you for your words of advice.
Particularly pleased that you posted pics of the Mk.4 as it goes to a question I posted over at the ARC and one of the resident "know-it-alls" (he hails from here) stated that the RCAF NEVER flew Mk.4 Sabres... Glad you have been able to demonstrate to the contrary.
How did you find the Scoobie wings set? From all the pics of it that I have seen, it sure looks pretty rough - is that a fair comment? and it seems a touch on the expensive side. I have gone so far as to purchase a few of Hasegawa's 1/72 F-86D Sabre Dog kits with the intention of swapping wings - a little drastic perhaps, but they actually cost significantly less than the Scoobie wings sets! Nothing like going to extremes to do a project! LOL
Again, superb Sabres!
