Linkert Deflector Part 2

A Cast Aluminum One
Steel and Aluminum

Same number on the inside.

I don't remember where I got either of these but somehow over the years I ended up with a steel one with the word Linkert and Choke Instructions on the outside and a cast aluminum one that is smooth on the outside and obviously was cast from the steel one due to the same number on the inside of each.

Not sure who, when, where or why...
