Hi Steven,
Which parts of the Mark II horizon-mirror assembly would you need detailed drawings for? I have a Mark II, so I could draw up some CAD models and/or fabrication drawings for the horizon-mirror cell itself, another part that Bill Morris calls the "index error bracket", and a third bracket (!) that holds the horizon shades and attaches to the main frame. There are also some specialty screws with square heads for adjustment. The brackets are, I guess, cast iron (you might want to use steel or bronze instead; once everything is painted black, they'll be pretty close cosmetically), and I think the screws might be cupronickel.
Cheers,
Peter
