OK ... to refine your estimate a little further, your Early Wartime Police accepted HSc production date is December 1941. It's hard to talk to the condition based on one photo. Of course, the Grip panel is chipped on the upper corner and it looks like a larger than normal screw head was/is used to hold it on. Bluing is somewhat worn, perhaps 80% to 85%. Don't know if the Magazine is correct without at least a description.
That's about all the information I can provide you with. Anything else, I'm always here.
