monica-taddei,
Thank you so much!!! 
OMG, what an invaluable resource, and I had no idea it existed!
The virtual tours are great, but the real gem of the website is SurgiCat:
SurgiCat

The SurgiCat Search Page
http://surgicat.rcseng.ac.uk/search.aspx
It allows you to search the museum database, I tested it and ran a search for ‘skeleton’, and retrieved this:

I mean, you can probably find whatever you want in terms of skeletal reference!
You can zoom in and click through a set of related pictures:
Thanks so much, I’ll add this to the Anatomy Reference thread right away. 
EDIT: Ok, I’ve added this link to a new subheading ‘Museums’, here.
Cheers,
