VX275, I'm not sure why I've been naughty... It's a very historic aircraft, in its way, isn't it?
It is a piston twin...
It is in a museum...
Etc.
I think the squirrel cage is an air filter or separator, can't find a definitive answer but perhaps 275 can help.
Port or starboard engine? Well, there's an assumption there that the aircraft has port and starboard engines, isn't there?
