Listing is for 2 inches of my 8 pound Rail used in the Gold/Silver mines of Montana that I personally removed from a Mine and brought back to Nebraska. It’s a slice off a piece of a 15 foot string of Rail. Similar in the dimensions of my Keychains that are around 3/8” inches thick that I have on a different listing. Size is actually a little over 2 inches at 2”1/8”. Rail was made In Colorado Steel Plant( probably at Peublo, Co. plant) in 1881 and shipped west to the Mines.... Please e-mail me if you have any questions. I have been making various sizes of these that are being used as paper weights or just something cool to put on your desk or add to your collection. Thank You!
