  The M1848/67 Kammerlader Landmark is the most common of the Norwegian navy kammerlader conversions, although all Norwegian naval chamber loaders are scarce.  It is a short rifle by comparison (__ mm, __ ins. overall) and when converted to metallic cartridge, it was fitted with a new ______ (sloping?) rear sight to accommodate the new cartridge.   Significantly, the navy rifle was maintained in it’s original 18 løødig (18 bore, 16.8mm) caliber thus combining a wholly inadequate cartridge with an astoundingly complicated action and operating cycle.  Very few Marinekamerlader ever went into service.

  The M1860/67 Landmark (4’’’Kammerladnings gevær ombygget til Landmark) is the navy’s conversion of the M1860 Short rifle (Kammerlader Kort M1860) and is generally seen with only two spring –retained brass barrel bands.  This rifle is chambered for the 12.17 mm Remington rimfire cartridge.  An interesting and somewhat ironic modification is the adoption on this rifle of the army’s 3-pin system for retaining the operating lever.


  In the army’s Lund conversion system, the entire breech block is replaced as well as the brass plate under the chamber replaced with a steel one and a track for the new extractor fitted to the inside of the receiver.  Compared with the Norwegian Army’s Lund conversion, the navy’s Landmark conversion is cheaper and simpler, replacing only the front of the original cartridge chamber with a new piece, hinged to the remaining piece of the original chamber, with the extractor sandwiched between the old and new pieces.  The only modifications are to the chamber itself, adding the cartridge chamber extractor and a new short, ---- firing pin to the breech block. This results in a system equally as strong as the Lund’s with easier loading and with fewer extraction challenges.  Of course, compared with almost any other breech loader of the time, the system is overly complicated, slow and clearly obsolete.


  The rifle is operated by rotating the operating lever on the right side of the receiver counter-clockwise, which first retracts out of battery,  then raises, the chamber via an eccentric cam.  Further lever rotation pivots the chamber assembly back over the rear of the receiver separating the chamber halves at the hinge in the center of the assembly, concurrently extracting the quite short spent cartridge case.  A fresh cartridge is inserted “backward” into the now rear facing chamber halves and the whole assembly is now “rolled” forward via the operating lever being rotated clockwise.  But to seal the chamber back into battery the lever, near the end of it’s stroke, must be slightly rotated backward and forward again to position the assembly for closure.  If this operation seems complicated, it’s even more so to accomplish than described!
