Mule88; Coincidentally to your post, I shot 50 rounds this afternoon "in my backyard" this PM(240 gr. lswc over 6.5 Unique out of one of my T.L.s. A fairly rare 7.5" Target model, all original, with probably 85% finish.
Scarce gun,but would probably not be "worthy" enough for some of the "serious collectors" here
But, to me, it is a piece of history, and one that I am the caretaker of while I own it and are able to,-but one that I want to enjoy. Gun has suffered no additional finish wear in the 15 years I've owned it-but I keep it well protected. and shoot it maybe twice a year, with "prudent" handloads. I am fortunate in owning "enough revolvers"
to shoot several times a week, but not too much out of any of my vintage revolvers.
Continue to shoot and enjoy your T.L. Sadly, there are some who own them, but never have the experience of "going back in time". I have had several "shoot offs" with this T.L. and a 1907 Colt N.S. Target, and suddenly, its the 1910 era. :
A nickle gun does show its "wear" more than a blued one, and the patina of my T.L. seems to blend in with the 85% or so remaining blue.
Plus, you will never recoup the expenses of a high quality restoration-at least in your lifetime(unless your a "youngstah"). Just hate to see a piece of history have its originality "vanish".
