Luger commercial model 1900 7'' barrel.

[Dwight Gruber]

The 7" barrel Old Model Parabellums were a batch of early carbine tests made for the Chilean army in 1902. According to Sturgess, these are found in the 10001-10020 serial range, some with duplicate numbers. Note the stock lug, it is for a pushbutton stock. Some had a six-position adjustable rear sight.

Sturgess discusses this variation in some detail between pp. 218 to 256 and salted in elsewhere (the red edition).

My example, sn 10012. Standard rear sight.
