ebay can be a good source for all sorts of medium scale Fenders from Japan.
Just do a search on "Fender Bass Medium 32" or "Bass Guitar Medium Scale 32" - a few will always pop up.
I love my 1962 Jazz Bass replica in medium scale, it's friggin awesome!
Here is the Fender Japan site where you can see the finishes, but please note that Fender Japan only measures scale length from the nut to the 12th fret. You need to convert from mm to inches and then double it: http://fenderjapan.co.jp/jb62m.html
You can get it brand new here off ebay in burst: http://www.ebay.com/itm/Fender-Japan...item27d72b9969
But used ones come up as well - and don't be afraid to check around - like the US the Japanese mail order/internet distributors will definitely save you some bucks on the instruments and on shipping.
