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.
Upper section has been pinned at least twice.
