Continental Motors Pin from Lehmann & Wundenberg

[gabatgh]

Hi! So I have this small pin. On the reverse it says Lehmann & Wundenberg Metallwarenfabrik, which I know to be prolific on German military items so I thought I'd bring it here.

The pin is enameled and has the name and logo of Continental Motors.

I'm hoping maybe someone might know the age of it, or deduce the age by the way the pin is made?

Thanks

I have a similar lapel pin. Both were made for Continental AG, the German manufacturer of tires and auto parts, HQ'ed in Hanover, Germany.
