Coleman quick lite help

This looks like my other Coleman quick lites but the only place it's marked is on the handle. Any help would be appreciated.

 

Just to confirm: nothing on the air tube or control wheel?

Also, where on handle is the stamping? Column, or top?

Tony,
Looks like someone has this apart the handle is upside down and the air chamber has a f on it.

 

“A” on control wheel gives me the estimate of 1922.

Thank you
