Here is a highly detailed model of the ABSD7 USS Los Alamos Floating Dry Dock.  Length 130mms or 5inches.

Scale is 1/1250.  This is one of a number of models which we have inherited when we bought the former Mountford range from MT Miniatures.  It has been assembled and completed to a good standard and is in a good box and with a CNCollectables catalogue number D30.
