Blue Adam was a Syracuse stock pattern, but it has been documented as having been used for a time on the Prospector train, owned by Denver and Rio Grande Western Railroad; it was never railroad backstamped.
My initial listing is for four of these pats, to be sold individually. They are all in excellent condition. Two appear to be unused; two have light use marks. There is a slight variation in coloring among the four, as was typical of this pattern. As the pats are sold, I will send whichever one I deem to be in the best condition, though they are all excellent representations of this pattern.
