Looks like you were on the right track...
I yanked the RD off the bike and gave it a once over. When I took the pulley wheels out and cleaned them I noticed this:
This plus the Falcon freewheel on the bike - along with a Falcon FD on it as well - I guess makes this one some sort of a Falcon variant. It is very similar in appearance to this Falcon model and the center/center measurement of the pulleys is the same:

I'm building a parts bin bike and this RD should do the trick capacity-wise so I'm going to give it a whirl.
Posting here for posterity in case anyone else ever finds one of these things and wonders what the heck it is
