Good Morning!
That is a great looking knife!
Miller Brothers' knives are very collectible. According to Goins, that mark was used by miller Bros from 1863 - 1926. Goins has a nice write-up about Miller Bros in his book. The Meriden on the tang is Meriden Connecticut.
Oh yes, it looks cool alright. That is an early style.
Yes, I keep trying to make out something from under all the rust on the tang of my knife. I recon I will just have to wait to really tell.
Great bunch of guys here on the forum. Some a LOT more knowledgeable than me.
Join in and ask question. Everybody loves to see pictures of knives!
