120mm Granatwerfer 42 kitbash

A mash-up of the Zvezda and DML 120mm GrW. 42.  From what I can tell, the Zvezda is actually the Soviet 120mm m.1938 (of which many were captured and used by the Germans).  One obvious difference is the sight.  Also, horizontal adjustment mechanism is a knob on the GrW. 42, but a crank on the m. 1938.  Both the Zevezda and DML have a crank.  A good reference is a US army film demonstration of the deployment of a capture GrW 42 - easily found online.

The trailer also is the Soviet version.  Have tried to modify the trailer slightly, esp. at towing hook which consists of spare parts from the Tristar 20mm FlaK 38 (although it should be bent).  The lower vertical cross bar probably should be deleted.  Based on reference photos, the cart wheels also should be replaced w/something like Opel Blitz/Steyr 1500 wheels.  The (temporary) wheels shown are Hussar Productions flak trailer wheels.  To fit the DML mortar base plate, the portion of the trailer where the base plate hooks on had to be thinned.  Also, the Soviet trailer supports appear to have been more angular than the German trailer and so there was some slight rounding.

The towed mortar is the Zvezda tube and folded legs, with everything else from the DML, plus the horizontal adjustment crank replaced by a knob (from a spare rear mg mount from a DML 250 or 251) and a cross bar with a holding pin (part of the aforementioned spare rear mg mount).  The deployed mortar (Soviet) is the DML tube and legs (and replacing the Zvezda vertical crank with the now-redundant horizontal crank from the DML kit), with everything else from Zvezda.
