when they made it the window would have been installed before coating,surely.correct me if i am wrong.you dont remove inserts to clear,do you?

Not sure to be honest Damien if it was in before or after clearing. Inserts are small and generally not a clear window. I believe clearing over the top would make it very difficult to see through. But not sure I anyone has done one yet anywhere.. 

Anyway maybe another topic as I would be interested to find out...

Great work Tim on a very rare playfield and Nick it looks fantastic
