Identification help

Hi,
Can anyone help me with identifying these two LeBlanc clarinets?
Number on LL 10608


Many thanks

The LL model was introduced in 1960, so that one must be from 1960-62.

As for the other one, I'd guess the first half of the 1950s. Probably equivalent to or the predecessor of the 476 "Classic" since it isn't a Symphonie or Dynamique.

That tracks, Rocket. 

James-
I have #5923 (pre-classic) which I have confirmed was made in late 1951, so yours is early 1951.

Nice horns.
