ok got my hands on a nice second hand mini playfield (untested yet), so now can consider what to do with the old one.

I have attached a couple of shots of the old one and one of the recently purchased one. Disregard the faded look on th eones that I used a flash. I tried to really show the planking etc.

So what do you think I can do to improve the old playfield, ie. overlay or other thoughts?
