Are you sure about that car number?
Because unless they have acquired 817 from GA/FL area recently then the only two SR LW coaches based out of there are 819 and 829 (Restored and currently at and leased to TVRM)
Thanks so much for sharing these detailed pics, this was on my to do list soon but you doing this is such a great help.
I believe this is one if not the only of the SR LW coaches still with it's original underbody equipment configuration.
