Locobase also was suspicious of the builder's date, but Drury (1993) shows the same figure. The NOGN diagram also reveals that the unit cost for this class ranged from $13,462.29 for 106 (love the precision of the 29 cents) to $13,728.25 for 104.
They seem to have left service soon after the NOGN's absorption by the GM&N.
