Re: Can anyone identify this device on this flintlock pistol???
Whatever its intent it didn't catch on. This could be for any one of, or a combination of, many possible reasons. The fact that it was not widely accepted does make it relatively rare in number. This rarity does not necessarily make it valuable although it may have some value to collectors.
I am not speaking as an expert but as a thinking person with experience in firearms.
We, as a nation, have become fatified, lazified and stupefied.
