Trumpet JUPITER 812R with genuine case, rare, Jupiter

This is a Jupiter JTR-812R.
It occasionally appears on the used market, but I believe it's a rare item.
It seems to have been in circulation around 2010.
This is an instrument with a lot of careful design, and it's in good condition, so I'm reluctant to part with it, but since I don't have the opportunity to use it, I'd like to pass it on to someone who will.
