Thanks for the information Cowboy!Yes, that is a Tingle model 1962 TGT Rifle my friend.
Some argue that Bob Tingle was the very first to introduce coil spring main springs in his locks. Even before TC.
Barrels were Douglas. All other hardware were handmade by him and an employee that worked for him. Stock, Lock, and furniture.
Nose cap is pewter. Cheek peice on stock is concave. Wedge key is a solid stainless steel pin dowel.
He passed away fairly young during the blizzard of 78. Had a massive heart attack. He was 57 or 58 years old at the time.
Here’s some pictures of my Tingle model 1962 TGT Rifle in .45 cal.
Respectfully, Cowboy
My thoughts on the defarb are the same. I also thought that may be an original lock plate that the Tingle mechanism was married into but wasn't sure. My draw to it was that it used by the 66th Illinois during the war.
