Another Answer to the Relic Mystery

I got one more response related to my nut and bolt question.  There is an error in the first sentence I think.  I think it is supposed to read, "I would say this is not a track bolt..."

I would not say this is not a track bolt for a rail joiner as the threaded lenght of the bolt is to long. The threads are only long enough for the nut, a washer and the width of on joiner. The rest of the shank of the bolt is elliptic in diameter. So the lenght of thread of a 45# bolt would be about a inch and maybe a quarter. I thought that most of the rail joiners in the Alpine Tunnel area were a majority of the Fisher type?
