You guys are to fast for me
I agree Moto meter This one I believe made by Boyce.
Rickenbacker is a very strong possibility. I see the O and Meter consistent with Boyce lettering. Boyce would be in smaller print not visible (behind damage). THey made these meters as an add on And put everyones logos on them from MG and Citroen to Ford and Chevy. The Patent date looks like Dec 10, 1918 which would be consistent with their early patents. THe Hat in the ring logo is one I have Never seen nor can I find it on the web for boyce logos. It is Rare. I would restore it or at least remove the glass for a better view. NICE!
