The DRAGON 14132 1/144 scale kit depicts the German Morser Karl self-propelled siege mortar in its railway transport configuration. This kit includes the mortar itself and the specialized two-piece railway carrier designed to transport it. The kit is part of Dragon's Mini Armor series and is available in either dark yellow or panzer gray plastic. It also includes a length of railway track as a bonus. 

Here's a more detailed breakdown:

• The Morser Karl:

  This was a massive German artillery piece used during World War II, weighing 124 tons. Its size necessitated specialized transport. 

• Railway Transport:

  The kit represents the Morser Karl's transport configuration where the mortar is suspended between two railway cars. 

• 1/144 Scale:

  The model is in 1/144 scale, meaning it's a miniature version of the real thing, making it a relatively small and manageable kit. 

• Dual Color Options:

  The plastic parts of the kit are molded in either dark yellow or panzer gray, which can be beneficial for modelers who want to simplify painting. 

• Bonus Track:

  A length of railway track is included, allowing modelers to create a diorama or scene depicting the mortar in transport.
