Well, it certainly was top-of-the-line at the time it was built.
I know there can't have been many manufacturers who made 1) metal, 2) articulated, 3) Albert clarinets.
That may narrow it somewhat.
The lower keys have rollers, which means it's not too early, but then again Albert largely died after like the 20's, right?
My metal simple system has no rollers, which should date it to... 1880s?
So this one is probably turn of the 20th century, I'd imagine.
