This part is intended to be used in building a semi-scratch 1/32 model of the Lunar Module. These are attachment points for the LM ascent stage. For indications on building the model please refer to
http://spacemodels.nuxit.net/1-32 LM. This part does not contain the HGA cover and is more suitable for LM after Apollo 14 where Quadrant 1 was occupied by the LRV.
