Help identifying luger p08 commercial

[padredan]

thanks, i could not see how the chamber date could have been removed and it still look this good, i have fired it about 50 times with factory remington loads with out any problems, i fully field strip it and cleaned it when i first recieved it and to check it for any problems before firing it, i had no idea it had been a .30 being changed to 9mm. nor did i know anything about the recoil spring swap. the gun to me is very nice and i just would like to know as much about it as i can. the unit markings L. Hi.65 i am being told means weimar era,L aassigned to landiger (rural constabulary),Hi Hildesheim distric, .65 meaning item 65, what can anyone tell me about the proof marks anda appromate value for it, allso are the mag bottoms wood or resin, sorry for so many questions, but this is the first luger i have really considered as a keeper, again thanks every one for your help, regards Dan
