A. Robert Paris, Articulated
This is another example of an A. Robert Paris clarinet.
This one, however, features the articulated C#/G#. Articulation usually signifies an instrument of somewhat higher quality. As you can see from the pictures, the condition is pretty poor and it does not currently play.
Update [Phil 15Jan2016] This is obviously from the same maker, which appears to be F. Lorée.
This clarinet currently resides in the collection of David Watson of California.
Upper section has been pinned at least twice.
