Up!

That seems like all NGG have the same problem with the inserts. I have a proposal to fix the inserts :

Fill the insert with resin.

HOW? You'll need to perfectly align the playfield at 0 degrees and fill the insert with a resin (with a syringe) . Not all inserts are clear/transparent so... I suggest mixing with coat that is close to the desired color. After drying , apply the label using a waterslide paper.

If someone have those legends I can try on my playfield and share the results with a step by step guide.

I still looking for an insert decal set... anyone?

Just looking at someone scanning the insert decals. I can touch up and share the image file here for anyone can print.

I took some pictures of my missing insert decals (before cleaning) . If you have a NGG and can scan the highlighted areas on the pictures I'll really appreciate

the picture may have varying angle , the flash can interfere with colors/light as well. The scan " guarantees " that the angle is always the same as the light.

Possibly yes.

I bought a hand scan yesterday. I know a guy that have two NGG... here.. in Rio de Janeiro. I'll scan the inserts of his machines. I don't know nothing about the condition of playfields... but.. may next week I'll go there.
