old Luger no date need help

[gatewayad]

Hi could someone please help me figure out what i got
it has just the DWM marking on the top, no date or any other markings
bottom side of barrel is a small crown with an N under it below that is the serial number 6101 and below that look like a script lower case L
all metal parts are numbered 01 except the wood grips and magazine (no numbers on these)
on left side of barrel above the takedown is another crown and N
right side of barrel has no markings at all
the crown N is also in a couple other spots

NOW the really strange thing on left side German writing for safety GESICHERT standard but on the other side very small towards top is GERMANY (in english)
minor bluing issues but inside looks really clean no rust.

I would like to know if anyone of you experts know what i have






I would be very curious to know appx age history and value, please let me know if you need any more info
thanks in advance
Joe
