Ricardo,
I have the markings you need in 1/72 scale. I have used a few bits off the sheet, but the HC-1 markings, warning arrows, national insignia, and roof
walkway markings are intact. A word of caution; Microscale decals get
notoriously fragile with age. You will need to coat these with Micro Decal Saver
or some other form of resorative agent or they will disintigrate as soon as they touch water. Each decal will need to be trimmed from the sheet individually.
E-mail your address and I will gladly send them to you.
Cheers!
