as iDwight, what makes you think it was re-barreled? I don't neccesarily diagree that the T/P doesn't mean technical police, but I have been told that it is more likely just an acceptance marking by either Simson or the tech polizie.
It does come in other configurations, see Costanzo (I am traveling today, so no books available, well Weimar is in my suitcase, but that is normal on a travel). From what I understand the T/P can be intertwined, P/T etc.
Ryan, show us some clear photos (not so big they fill the entire screen) of both sides.
An all matching Weimar reissued luger in nice shape goes from $900-$1300. Much would depend on if the holster goes with it, what shape the holster is in, if there is a spare mag or tool with it, etc. It does have ONE matching mag, not really uncommon with police, but not incredibly common either. The 67 is interesting, as it is repeated for the grip strap marking.
