1929 S suffix commercial marking/proof ID
 

It appears to be a crown over a Gothic G. Found something about it being a Simson rework mark for a specific contract? Any ideas? No sear safety, No mag safety, Upright Crown N on bbl, left receiver side and toggle, blank chamber, DWM toggle. No other markings. 30 cal. A strange cleaning rod in the holster as well. Crappy pics and lighting, sorry.
