In fact, reading the regulations, it is confusing, surprise, surprise;

Luger, Artillery model, pistols having chamber dates of 1914 through 1918 or 1920, having
German Weimar Navy markings consisting of the letter M over an anchor and a German
Navy property number accompanied by original Artillery Luger flat board stocks, bearing
German Weimar Navy markings of the letter M over an anchor with or without Navy
property numbers.

They mix the artillery and the navy into the same paragraph without separating them...

Luger, the 1920 Commercial Artillery model, pistols as mfd. by DWM or Erfurt, having undated chambers, commercial proofmarks, and bearing the inscription Germany or Made in Germany on the receiver and accompanied by original, German mfd., artillery type, detachable wooden shoulder stocks.

Luger, DWM Pistol, model 1900, 1902, or 1906, in 7.65 Luger or 9mm parabellum cal., having the
American Eagle chamber crest, and barrel lengths of either 4" or 4-3/4", with original detachable Ideal shoulder stocks and Ideal frame grips.

DWM Luger, Original models 1904, 1906, 1908, 1914, and 1920. Naval pistols in 9mm
parabellum or 7.65mm cal., in both the Commercial and Naval military varieties; in both
altered and unaltered barrel lengths in the model 1904 and in both altered and unaltered

bearing brass or iron discs, with or without markings, or, if without brass or iron discs,
being of the Navy flat board-type. This exemption applies only to the listed Naval Luger
pistols if mated to the Naval Luger stock and will not apply if the Naval Luger pistol is
mated to the Artillery stock. The Naval stock has an overall dimension of 12-3/4", a rear
width of 4-5/8", a front width of 1-1/2", a rear thickness of 9/16", and a front thickness of
l-3/16".

Luger, DWM Stoeger model 1920 and 1923, semiautomatic pistols in 7.65mm or 9mm parabellum

and/or Stoeger frame and/or upper receiver marks, having either standard, Navy or artillery
rear sights, having extractors marked either "Loaded" or "Geladen" and having frame safety
markings of either "Gesichert" or "Safe," together w/original commercial flat board stocks
of the artillery type, which bear no S/Ns or military proof marks; may include a "Germany"

Luger, DWM Pistol-Carbine, model 1920, 7.65mm or 9mm parabellum cal., with accompanying
original commercial type shoulder stock, with or without forearm piece, having barrel

Luger, Persian (Iranian) Artillery model, pistols, as mfd. by Mauser prior to 1945, accompanied by the
original artillery type, detachable wooden shoulder stock, bearing a S/N in Farsi characters
stamped into the wood on the left side.

Luger, semiautomatic pistol, certain variations with Benke-Thiemann folding shoulder stock.

These are slightly different than LAST time I looked, personally, I think the question should be asked on whether stocks themselves are illegal. ?
