Cob 150a was found with a Roller Organ dated 1920 and may be a late change. In the photos, the notes circled in green are some of the added notes not found on cob 150. The single note circled in red on copies a and b is beyond the end of the song and does not play although it may have been on the pinning pattern. Another copy of 150a is needed for comparison.
