PARKER GUN Tobacco Tag

[Gunner]

Tobacco tags are a collectible that I didn't even know existed. Reportedly there are thousands of different tags. Here is a "PARKER GUN" tobacco tag that I would like to know more about.
There was a thread about this 9 years ago but unfortunately it is lost in the archive and can't be retrieved. Does anyone remember any info from the thread? Can you offer any information on the Parker tag from personal knowledge or other sources?
How common is the PARKER TAG today?
Was it used as a promotional item by Charles Parker Co.; was it licensed; or was it an infringement? Did sports or men that couldn't afford a Parker pick up a plug at their local sporting goods store?
Thanks in advance for any information. This tag is about 0.50" x 0.74" for reference.
