German 10,5cm leichte Feldhaubitze 18M


The German 10,5cm leichte Feldhaubitze 18 Muendungsbremse (10,5cm le FH18M) came into production in the 1940s.  It is the longer range variation of the Rheinische Metallwaren und Masschinenfabrik (Rheinmetall) 10,5cm leichte Feldhaubitze 18 (10,5cm le FH18) which went into production in 1935 despite the 1918 designation.  The 10,5cm le FH 18M is distinct from the older 10,5cm le FH 18, having a double baffle muzzle brake (Muendungsbremse) and improvements in the recoil mechanism.  Its maximum range is 12325 meters, which is a 1650m improvement on the older 10,5cm le FH 18.  Both howitzers have essentially the same carriage with a spit trail configuration and a single equilibrator mounted to the right of the barrel.  The 10,5cm le FH18 was built to replace the WW1 Era 10,5cm lFH16, however, all three howitzer types continued service in the Wehrmacht until the end of WW2.  The 10,5cm le FH 18M and its sub variants can still be seen in service with some nations of the Middle East and Eastern Europe.  The 10,5cm le FH18M howitzer was used in some numbers by Iran in the 1980s, Iran-Iraq War and shows up from time to time with militia units in the ongoing war in Syria as late as 2019.  In the Former Yugoslavia Crvena Zastava produced a variation of the German 10,5cm le FH18M called the 105mm M56.  These have also been widely exported to the Middle East 














As with most German ground equipment in the WW2 Era, the 10,5cm le FH18M was generally horse drawn.  A six horse team with three drivers pulled the Limber (Protze) and howitzer.   In addition to horse teams, the 10,5cm le FH18M could be transported by a number of motorized vehicle types, including the Raupenschlepper Ost (RSO), and the Opel Blitz. The howitzer in these photos has Post-WW2 Finnish Army wheels

The traversing mechanism hand wheel are also in this photograph.  The Recuperator cylinder is disconnected from the breech ring
