We don't get to see many Airfix kits on here. I remember butchering lots of them as I grew up. I've boughtt all the reissues and even comparing them to modern kits they have stood the test of time well. There is a lot of the cars that haven't been reissued like the MG1100, Zodiac, Mini and Sunbeam Rapier so I guess the tools have been destroyed
Shunko Models have been releasing replacement decals for these Alfas over the past few years. I purchased the Bosch decal set and the quality is excellent Hobbylink Japan is still showing the Bosch and Jagermeister sets.
As decals can vary from each and every company and clear coats vary in how aggressive they are I always place a piece of decal that wont be used on to a spoon then spray clear over that before committing to clear coating my model.
