Thanks to Mr. Beach's capital efforts, we now know that 106191 was in inventory at V,L&D by Summer of 1903, or arrived sometime in the 1st half of the year. He notes that there were several in the 106xxx serial number range that were in inventory in 1903. This is ground truth for the 106xxx manufacture block being in 1903 but there is the slight possibility that one was set back and completed later.

Kind Regards,
