This is an injection-plastic aircraft model kit.
From the manufacturer:
Of the RAF bombers involved in operations over Germany during WWII, the Avro Lancaster must rank as the most famous of them all. As the strategic bomber offensive gathered momentum, it was the Lancaster that came to the fore after entering service with the RAF in 1942, overshadowing its other four-engine contemporaries, the Handley-Page Halifax and the Short Stirling.
The Lancaster flew 156,000 sorties and dropped 608,612 long tons of bombs between 1942 and 1945. Just 35 completed more than 100 successful operations and 3,249 were lost in action. It was the Lancaster that spearheaded the battles for Berlin and Hamburg, and it played a vital role in the devastating raid upon Dresden. The Lancaster has become the symbol of Bomber Command, and as such, a symbol of British air power during WWII.
Completed kit measures 294mm long and 432mm wide.
