When Olympia was saved, she was a hulk and required a lot of work to restore her. Back in the 1990s I befriended one of the volunteers, he was the gunner. He told me that of the 5in guns came from the USS Colorado - Same make different mod - so they are pretty close. He also took me into the non-public areas. The other (port) engine room is stripped of all machinery. The dynamo rooms are also stripped.

I have not visited her in quite a while and need to go back.
