I still have several sets, and the signage can be very useful, especially the Allied set. Sometimes they work perfectly, other times leave a part behind. Should the surface be matt or glossy, eg prepared with Klear or other? Or even initially rubbed down on the backing sheet?
I also have some Archer and Fingerprint designs - are they similar please?
Whilst googling the subject, i came across this fascinating Letraset history - and , yes, I still have loads... ! For sale if needed. I really used to love them.

Good for a CAFE sign in a glass window too, I even have some in Gold print.
Reading that I know I'm getting old...
A lot of the original rub down transfers had a limited shelf life. The adhesive sort of dried out. Once this has happened they are hard to use. So once they have gone you need to buy new ones.
One tip that can work is to rub them down on to clear waterside decal sheets and convert them to a water slide decal.
Archer transfers are different. They DO NOT HAVE A SHELF LIFE. Check their web site and it explains the difference.
I don't know about fingerprint decals.
