WWII German Karl Mörser Railway Mortar – 4158-Piece Building Set


Unleash the Might of History’s Largest Self-Propelled Mortar -Step back into the intense battlegrounds of World War II with General Jim’s German Karl Mörser Railway Mortar Building Set — a stunning 4158-piece tribute to one of the most formidable artillery weapons ever constructed. Developed by Germany in the early 1940s, the Karl-Gerät was a super-heavy siege mortar designed to demolish enemy fortifications with devastating 600mm shells. Only seven were built, each with immense firepower capable of leveling bunkers, bridges, and city blocks.

These mortars saw combat in some of the most pivotal engagements of the war, including the Siege of Sevastopol, the Warsaw Uprising, and operations on the Eastern Front. Deployed via custom-built railway cars or crawler-chassis, the Karl Mörser represented the peak of WWII artillery engineering and battlefield intimidation.

Key Features:

  • Historically accurate design based on the real Karl-Gerät tracked railway mortar
  • Detachable mortar section for simulated battlefield deployment
  • Includes front and rear tractors, a crawler vehicle chassis, railway cars, and track segments
  • Interior details: rotating cannon barrel, built-in cannonball loader, engine block, crew compartments, and functional toolbox
  • Push-to-load shells, spinning loading mechanism, opening panels, and auxiliary support wheels
  • Measures over 30 inches in length when fully assembled
  • Designed for advanced builders and historical model collectors
  • Compatible with all major brick building brands

A Legacy of Firepower

The Karl-Gerät wasn’t just a weapon—it was a symbol of raw mechanical power. Transported via rail, then transferred to tracked movement for final positioning, it embodied Germany’s heavy artillery strategy. Each massive shell weighed nearly two tons and could be launched up to 10 kilometers, leaving craters and chaos in its wake.

Perfect For:

  • Military history buffs and WWII model enthusiasts
  • Diorama creators and collectors seeking centerpiece artillery
  • Builders looking for a high-difficulty, high-reward project
  • Product comes unassembled with detailed building instructions.
  • General Jim’s building blocks are compatible with all major brick building brands.

This is very hard to find item.
Size: 1 Quart, Style: 6-Pack, Configuration: Euro LX 0W-30
This is one of the lowest VOC oils. Important if your vehicle is GDI. Should help keep valves cleaner.

Went with a 30 weight because of ambient temperatures
Size: 1 Quart, Style: 6-Pack, Configuration: Euro LX 0W-30
Running this in my wife's 2016 Subaru Crosstrek. We live in Arizona and 100+ temps is normal thing. Did a lot of research on this before I decided on running a 30 weight, technically a 40 weight is recommended for our temperature. I noticed that her car was rattling on startup and was worse when it was a hot start. After switching to a 0w-30 I noticed the noise was substantially less. Fuel mileage was not changed she's still averaging 32mpg with her manual transmission vehicle. I've done my research and yes I know about staying with the factory recommended weight but we don't see subzero temperature and we are definitely not seeing the the average 80f summers. 40Fwinters and 105F summers are the norm here. Yes ambient temps effect oil decisions. I also prefer Euro Spec oils over SAE because of Europes extended drain intervals of 10-12k miles. I change every 5k or 6 months.

Fits perfect in my 09 Accord 4-cyl
Style: CA10467
Super easy to install, good quality, fits correctly. What more could you ask? A performance gain, you may ask. Ha. This is a gutless 2.4L 4-banger. No performance to begin with, and no gain after installing this. :-)
