These have been posted for a while (since October 2012), but I just came across them over at the San Diego Air & Space Museum (SDASM) photostream at Flickr. Over 20 photos of the Convair / General Dynamics Manned Orbiting Laboratory proposal mock-ups (link to taggedConvair / GD MOL mock-up photos at SDASM). Note a sign that appears in a number of the contact sheet photos reads (when viewed in full resolution) "GD A Project MOL ♂[/size]".
Here are a couple from the collection.
Apparently a Gemini/MOL model:
