I just picked up a used TVM Leman 58 flintlock rifle by Matt Avance at a gun show last weekend and it’s a very nice rifle. Shoots and functions great. I see no mistakes at all and I am very picky about build quality, plus I have & have owned many big name builders rifles to compare. I am not knowledgeable about historically correctness as I am a shooter but reliability of function, accuracy and build quality are important to me.
