EBT last use *LINK* *PIC*

"EBT has 6 ng mikes and two sg 0-6-0s left. When were they last used (before the shut down in April, 1956) and where are they now (for the switchers)? Which ones are currently operable?"
The following is a summary. I can likely be more specific if this is more than an academic question.
