Joe_G.I'm trying to answer quick before Jay steps in and ends the guessing game 
If Schriver, as I propose, I realize it isn't accounted for in the N172s and contend as above that it might be a N173 only pose (not uncommon).
I'm going to dig a little further into Shannon & Shindle. Shindle was shown with Philadelphia during N173 run & the Baltimore uniform looks very similar to Phily.
