I've been told that you can resurrect old, yellowed water-slide decals by taping them to the inside of a window with exposure to the sun. Somehow the sun takes the yellowness away. Not sure how long it takes (wouldn't want to leave them any longer than necessary so as not to fade the colored decal designs ). But it might be better to use the originals to copy and make your own decals on your printer. I've had some bad experiences with some water-slides form old kits. Even though they looked fine, when they were floated in water, they just desentegrated into thousands of nearly microscopic particles.

I built 2 Kougars in the past. Loved the decal set provided in the kit. Sig quit putting them in the kit after I built both of mine but they used to have them for sale as an option.

Pics below show same son holding my two similiar versions but obviously quite a few years apart...
