My first Luger, DWM shooter

[Max The Chainsaw]

New user and first post. I have loved Lugers since I was a teenager. It took me until age 59 to finally get a chance to get one. Funny story, this Luger showed up at a local gun shop and I was looking at it. Went back a couple days later and it was gone. Shop owner said someone had put it in a layaway and was making payments for it. Fast forward to Christmas and i found out who, it was my wife and kids!

I'll try to get up pics. DWM serial number 9690 no suffix. Toggle mismatched number, Mcgar magazine. Came with 2 sets of plastic grips and a pair of black pearl grips with wood backing. I suspect it is a police gun due to the sear safety. Great shooter, most accurate handgun I have ever shot and the most comfortable to hold as well

I can't quite figure out the proof markings. Can anyone give me any info on this gun.

Thanks you.
Max
