All I did was follow up on Fingers' suggestion above and Google it.
The Tingles seem to have square trigger guards, none showed engraving and others had brass receivers.
Then I came across the thread about the Palmetto and its target grip fit the description.
That's team work!
Despite their reputation, some Palmetto models are really nice. They made a Colt revolving rifle and a nice looking Blunderbuss percussion model that was pretty expensive that Dixie was selling. That pistol could be worth a little bit more if it were really a good shooter and has a nice trigger. The anatomical grip sure could be appealing to someone.
