Eric,,
My first was a worn out Erfurt in 1967, bought it at a "trade" lot; stopped to shoot on the way home and it would not "work"-

typical jams - that I could fix now but not then. I drove straight to a gun shop and traded it for something else.
Fast forward 25 years, to my second luger; bought an "artillery". Beautiful - always wanted one- was inspecting it at my table after it was mine- noticed it had two rear sights- the one on the barrel and the one on the toggle! Tried to find the "old man" who sold it to me, but he was long gone!

(I should have spent my money on books- like we advise folks to do now.

.)
Fast forward another 25 years or so to 2013( I was kind of "bummed" on lugers)- to my third attempt at luger ownership.
My L1 is a nice police model 1917/1920 "double date" from Merseburg that got me started on my current slide into luger never - never land. I don't have a picture of it alone, but here it is with My L6 , another police model I bought from Don Maus. You will notice both of these are former artillery lugers with 4" barrels installed.
Now I have more than 80 of the danged things.
Here are pictures first of the recent spree and a "good" one!
