Although said to be a Generic set of instruments for WW1 aircraft, this Airscale Decals set cover both German and Allied gages. Each decal gauger comes with 3-4 copies, so you have enough to do several aircraft models.

Beautifully printed by Fantasy Photoshop, they all appear in perfect registration, and thin. Each dial is printed as a separate item, but I can't see any carrier film around the individual decals.

The instruction as pretty straight forward, and gives you a listing of what each decal is by number, so there shouldn't be too much head scratching as to what each decal represents.

A small sheet of clear plastic is included for those wishing to use it to make the clear glass covers for each dial. (I would suggest using a punch and die set for cutting these, and it might not be a bad idea to use it to also cut out each decal.

I pick my set up from sprue brothers for the price of $9.99 USD
I also picked up their 1/48 scale decal set and my remarks apply to the scale's decals also.
