new luger

well i finally picked up my new luger. i have some questions about markings...

produced by dwm dated 1921

the only part i have found so far that doesn't match is the takedown lever (i will be detail stripping tonight)

right side of the top reciever has 2 birds with what looks like www underneath (similar to #31 on the markings page here)

under the barrel under the serial number is 8(or 3)8(or 3)2

inside the frame in front of the trigger guard is a h and the circled n blow it

and on the front strap of the grip is K.A.6. (space) 7.

some of my descriptions of these markings are vague due to my very poor eyesight and the fact that this gun looks like it was dragged behind a truck on a gravel road (if it wasn't a luger i wouldn't have even looked at it)

the safety lever looks as though it broke and someone had brazed a couple pieces of steel together to work. the bore is pitted to the point i am fairly certain it will have to be relined. the end of the barrel will need recrowned. all of the pitting (sometimes about a 1/4" round and deep) will need welded up. the grips are gone. but suprisingly the internal parts look really good and the trigger after a lot of creep and takeup breaks cleanly at about 2-3 lbs. i would like some help with deciphering some of the markings. i think considering the condition and the amount of work involved in bringing this old girl back to a state were i would even consider firing it, it sounds like a good candidate for nickeling. what do you all think?
