Nice item !

Just got this nice authentic used sparkplug of one of the Royal Netherlands Air Force Historical Flight's L-21B:smile:

I'm assuming these were sold as fund-raisers for an airplane museum or similar?
I volunteer at the Port Townsend Aero Museum in Washington.
One of the items in the gift shop are pieces of flooring from Boeing's original "red barn".
$5 apiece.

Kinda lame IMHO, and not real big sellers.
Something like your sparkplug is much cooler IMHO.

Thank you ! You can find more information here:
