It's good to find an honest man. Good on you, Gary!
The previous discussion of this pistol was on the Wehrmacht Awards forum that I happened to be visiting. The pistol was a former LP08, probably used by the Prussian Landjägerei until it was returned to the PTV in 1929 to be reworked as a P08. At that time, the barrel was replaced with one manufactured by Simson (note the E/6). It was then reissued to the Landjägerei of the district of Trier following the withdrawal of French occupation forces on 30 June 1930. While the mag safety was probably deactivated by the police in 1937, I believe the gun was subsequently transferred to the military where the sear safety was removed. Although they are few in number, I have noticed that most, if not all, of the Landjägerei Lugers from Trier have had their sear safeties removed. For example, see this thread:
