Another, more generic name for these is Plateau clarinet - these come in Boehm and Albert key systems, but much less common in Albert.

The Albert is a bit old fashioned, and the register key is on the side.

The material is advertised on the case - Vulcan Fibre. I would say this is between 1910 and 1920.

It's neither Boehm nor Albert.  It's called a sax fingering clarinet. The lower joint's has a fork B/F# mechanism like a Boehm but is Albert like other than that.

I am not trying to be provocative.... this is a true question:

If the upturned bell is “ok” and the metal neck is “ok” for an alto clarinet.... which is short ENOUGH for it to be workable straight instead of curved (I believe there are examples of this)..... would it really be useless to have a curved soprano just for convenience if someone liked it?  Or, is there something about the curves and metal that make the sound WORSE? 

I am not knowledgeable enough to answer..... just thinking that the video’s instrument looks like an alto or bass clarinet just in a smaller (soprano) form.  To me, with there being both straight and curved saprano saxophones that both are well liked..... why not for a
clarinet?
