The wee bit of the baggage-caboose-coach combine caught my eye. I know of #843 / #844 - not sure if others were rostered at any point? https://www.frisco.org/shipit/index...h-caboose-combine-slsf-843-and-slsf-844.1389/ https://www.frisco.org/shipit/index.php?threads/caboose-coach-combine-844.1388/
The car behind the 641 certainly looks like one of the Hoxie Sub cars. The Frisco did have similar caboose/coach configurations. See https://thelibrary.org/lochost/frisco/magazines/fem1930_11/fem_1930_11_11.pdf
