Where did this come from?

Hey guys,

I saw this on reddit and it has been driving me nuts, it was posted in the “autos” section, however I am under the impression that it is from the 1940’s manufactured by an a car manufacturer that doubled up to produce aviation equipment for WW2. It was found from what I gathered to be around Kansas, Nebraska area.

It was retrieved from a deceased elderly mans house and brought to a car show to see if anyone knew anything about it. It resembles the Spyker logo, however from what I know Spyker/Spijker never built an aviation V8.

I swear that I have seen this before but am absolutely stumped!

Work your magic!

Thanks,
Rick
