[Lugers down under]

Thanks for the interest guys.
To answer your questions Ron,
The Take down lever is numbered on the underside of thr lever on the left side. The Barrel has the same suffex b. The area over the chamber is unmarked ie: no cross in sunburst or date or anything. I am no expert as I have only been collecting Lugers for about 30 years but this gun looks like it is the original finish all over,The blueing is identical to my 1900 Lugers of which I have a number. It has that same "luster" if that is the correct word.
What puzzles me is the long frame.
I am an engineer and have seen a lot of fitting and turning and toolmaking. If the stock lug has been fitted later its the best job I have ever seen.It is no different to any of my other Lugers with stock lug.Here is a gun with a long frame yet is very clearly a new style frame made for the coil spring and not the leaf spring. There is no sign of there ever have been a grip safety.
An interesting note. In Vittorio Bobbas book he mentioned that in 1912 DWM made a number of 9mm 120mm long barrel guns from PO8 parts and that they had a stock lug. Could it be?
The person I got the gun from had had it for many years.
I will post some more photos tonight. Also some of my new side frame marked Krieghoff.
Kind wishes to you all
Murray.
