Couple of police agency issued guns I have picked up, two in this past yr.
Houston PD marked on backstrap HPD 38, a W&K 3rd model 44 shipped 1931. I will check but seems to be from same shipment as Randy's (Quinn) posted above.
Austin Police Dept issued 27-2 3 1/2" nickel marked APD 261 on left side under cylinder window. Wearing KB ropers and AW Brill holster.
