LaCroix bass clarinet

Here's a really neat old French bass clarinet made by LaCroix.

I'm really not sure if LaCroix is a stencil instrument or not,  this one was very similar to the "LaBar" bass clarinet I posted about some time back.
A few interesting things about this instrument:  the body is 2 piece but also made of ebonite,  this is the 1st 2 piece ebonite bass I've seen.  Also it featured a double register vent which is typically only found on professional instruments.
The neck was fitted with a circular key just like you would see on a saxophone,  wow!
I really liked the sound of this instrument,  the double register setup was certainly on the finicky side but all in all a good clarinet!
