It's an engineering test mockup. This model incorporates an engineering model of the Descent Stage (used at MSFC, designers of the Lunar Rover, for studies and fit checks) with a fabricated Ascent stage (note the lack of detail in the hatchway area compared to some other LM images)  https://www.americanspacecraft.com/pages/lunarmod/msfc.html
