Re: Know anything about Leblanc Bb model 476?

I've been collecting info on Leblancs off of this BB and find various bores reported for the Classic II and even the original Classic.

In February, 2003 one post here stated:
"I bought the Classic II . . . . I checked with Leblanc. They said my SN 309xx was made in 1969, professional model, .582 bore." (14.78mm)

In Nov. 2008 a post here stated:
" . . . I think that Leblanc bore sizes may vary with models over time. I have just measured the bores of 3 instruments in my possession
LL (early 1960's) 14.8 mm
Symphonie (late 40's/early 50's) 14.9 mm
Classic II (late 60's) 15.0 mm
all are fully cylindrical throughout"

In June, 2020 I stumbled across a for-sale listing for an overhauled Leblanc Classic (not the Classic II) for sale on the web site of a tech. He listed the bore on the Classic he had for sale as .590". (14.98mm)

In a post in Sept. 2019 I reported:
"After returning to playing a couple of years ago I got around to actually measuring the bore (of my 1967 Classic II) and found that the upper joint bore measures 14.97mm at the top and 14.98mm at the bottom (plus or minus 0.01mm) . . . ."

There is of course no way of knowing how accurage these measurements were. And there is no way of knowing which, if any of these were shipped from the factory in France with these bores or were effected by Leblanc USA's reported reboring practice. But it is interesting that the Classic IIs (and maybe even the Classics) sitting around seem to come in different flavors. And probably with different playing characteristics.
