I have Left and Right JM Mnenomic ramps. No decals or flaps.
I got them when I bought out a garage-full of stuff from a guy that has been out of the hobby for 20 years.
Assuming they’re NOS, but do have some light surface marks.
I have in ad here on Pinside Market $150 each OBO
I’ll ship to lower 48 via method you choose for exact shipping cost.
