The police armorers installed the sear safties.
No, the barrel proofing only indicates who "proved" the barrel.
Spare barrels were proved when made, an original barrel would show proving by the Erfurt, or the proof house that proved commercial arms for DWM or another repair facility, or the police themselves if done in house.
I can't see the proof marks on your barrel, but the description sounds like proof marks of the police or army rebuild facilities, from the '20s to the '30s.
