IHC Vanderbilt tender coupler question answered

[SteamGene]

Mac80c, thou desireth knowledge for thy IHC Vanderbilt tender.  Knowest thou that mine is ancient, a first born.  Yet the coupler pocket is held but with a single screw, a standard one at that.  Unscrewst thou thy screw and into the pocket place therein thy Kadee #5.  It is no mastery for such a labor.  Perchance, thy tender, being of more tender years hast a strange device.  Yet I have Vanderbilts for the IHC 4-6-4, eke the 2-10-2 and they are as like unto the 4-8-2's Vanderbilt as one pea is to its brother.
