Does anyone have any idea what this Sinclair Aircraft sign is worth? I've seen some beat up ones going for $3800, but not sold.

I also saw a decent one bring $11,500 on e-bay (Kraft auction), but it had the green background around the border behind the letters. Is the one with the green border more rare?

I have studied this sign extensively against the ones from Muhatagundra-alibaba India, and it appears to be the real thing. If anyone thinks otherwise, please let me know why. This is the only pic I have.

Thank you all in advance for your help, Steve B.

This past months (MAY) PCM magazine has a great article on these. I know they never made a 42"
