This is a custom landing Pad for the original and reproduction model kits of Moonbase Alpha. The original model kit only came with 3 pads. This version also has the Eagle boarding Gangway. This pad is to scale with the ones from the model kit. (Those were overscaled somewhat.) I also have the true scale versions, which are to scale with the rest of the moonbase buildings. (It should have come up in the same search. If not, try just searching on moonbase landing pad)
