Anybody knows when they made these solid silver necks with the over-the-top octave key? I was until now just aware of the
underslung-type necks made of solid silver...

I've never before seen a Yanagisawa sterling silver alto neck with the normal octave key. Many of the sterling tenor necks have that feature because there's an extra brass brace under the neck, which would get in the way of the underslung octave key. Presumably, this is because the silver is a bit soft, and the brace is needed to help prevent a pull-down.

In any event, your neck has a general kind of 80s/90s look to it, but that's just a guess.

Yeah, it looks older to me.

The badge looks like it could be from the old 6 series.

It is probably from the 80s when the company was establishing its brand outside of Japan - similar to the coin badge on the Elimona horns.

It could also be from the 90s considering that their trademark isn't in red, but that could be because it was a sell-alone neck.

I have a near identical neck (regular - not silver) which came with an older 880 I purchased from someone, but I'm not sure when the neck was paired with the horn.
