Spark Plug Covers

A friend gave me these spark plug covers several years ago, but didn't have any idea where they came from. I have been using them on the 32 Hot Rod for the past 8 - 9 years, travelling in Canada & U.S. and only found one person who had ever seen them before. His info lead to a dead end on Google. I wonder if anyone in H.A.M.B. land has any information on them. I would greatly appreciate any clues to mystery. A couple of photos attached.

 

No info for you, but they look good

 

interesting, never seen em before, looks like someone left sparkplug sockets on all the plugs haha

Thanks for the lead alchemy, checked out the post you refered me to. My covers are the same as the badger covers.

 

Ive got a set of them at home. They belonged to my grandpa. I posted a thread about them awhile ago. They look bad ***
