Hi!
I visited today History Museum of Los Gatos and had little
conversation with volunteers there.
Museum's exposition is not too big, however it has many items which
definitely could be photographed to illustrate Wikimedia projects:
everyday one like 1920s milk bottles, phonograph, uniform,
agricultural instruments, etc. Some of them may be filmed in action,
such as device to seal champagne bottles with corks. Of course there
are many old photos of local history and documents such as 1870s
register of voters.
There is periodic exposition changes which may be used to take
pictures of items out of glass shelves covers on Sun light.
Brochure of Heritage Council os Santa Clara County list 27 such museum.
Meet-ups may be used to promote Wikimedia projects across local
history organizations, and such organizations themselves via credit
information.in images descriptions.
Eugene.
