I have a one that is number (A20887) it is I believe a Standard Farrier and is stamped 208.
I have met several of the past owners and they were all proud to say they had owned it at one time.
It is traced to a ranch that purchased it around 1920 and has always spent it's life in the Carson Valley NV.
Do not know value, quality or how it was built however do know to keep it.
