Hi guys,
I have the chance to buy this neon Buick dealer clock. From the attached picture it looks OK, but I can't find any evidence where Lackner made this particular clock. Most of the ones I see are Chevy clocks. I want to make sure this isn't a fantasy piece. I know it would be easier to tell if we could see the back as well but this is the only pic I have. Would love to hear what the clock experts on Oldgas think about this one.

Thanks,
Brian H
