Hi,

In August 2001 I went to the Johnstown Heritage Discovery Center (Johnstown, PA) in a professional visit.
At that time they were experimenting with artificials odors to recreate different settings and situations (a butcher shop and some others I cannot recall now). The odors were not "in the air", but rather in some containers that can be opened to have an impression of how the odors in those places could have been.
Maybe you want to ask them how was their experience. Beside this one I do not know of any other experience with odors in a museum. 
The website is http://www.jaha.org/DiscoveryCenter/virtualtour.html.
