I just came upon a backglass for a 1942 flipperless pinball called, "Hit the Japs". It is a patriotic (for then) conversion kit from a 1940 Gottlieb "Gold Star". It does have some delamination but still looks pretty good, despite being incredibly politically incorrect today.
If anyone as any input or information about this glass or the machine itself, I would love to hear it. I can post pics if someone is really interested, but let's just say it's somewhat offensive.
Cheers,
Alan
