Spare guns were used as coastal artillery in Denmark, Norway and France. The &lt;a href="38%20cm%20SK%20C/34%20naval%20gun%23Coast%20defense%20gun"&gt;coastal defense version of the SK C/34&lt;/a&gt; was modified with a larger chamber for coast defense duties to handle the increased amount of propellant used for the special long-range "Siegfried" shells. Gander and Chamberlain quote a weight of only for these guns, presumably accounting for the extra volume of the enlarged chamber. An armored single mount, the "Bettungsschiessgerüst (Firing platform) C/39" was used by these guns. It had a maximum elevation of 60° and could traverse up to 360°, depending on the emplacement. The "C/39" mount had two compartments; the upper housed the guns and their loading equipment, while the lower contained the ammunition hoists, their motors, and the elevation and traverse motors. The mount was fully powered and had an underground magazine. C/39 mounts were also installed at the Hanstholm fortress in Denmark, and the Vara fortress in Kristiansand, Norway. Plans were made to install two of these mounts at Cap de la Hague and two at Paimpol in France, modifying guns originally intended for an abortive refit of "Gneisenau", but were not executed for unknown reasons. Work on putting two more mounts at Oxsby in Denmark was well advanced but incomplete by the end of the war. Some modified SK C/34 guns also saw service as 38 cm Siegfried K (E) railway guns, one of these being captured by American forces during the Rhône Valley campaign in 1944. Like the 38 cm SK C/34 naval guns deployed as coastal defense, the 38 cm Siegfried K guns were modified with a larger chamber to handle the increased amount of propellant used for the special long-range "Siegfried" shells. The gun could not traverse on its mount, relying instead on moving along a curving section of track or on a "Vögele" turntable to aim.
