Ah, I remember this beautiful Jian Bill which looks as right as rain. Have kept those pictures. If I remember correctly, it's indeed from the same seller Kai Wee got his.
And Kai Wee, nice "duan" (short) Jian although I've not seen a scabbard as yours. I like the "fa guang" (shinny) look of blade and seems you're as good in removing rust in Jian as for keris. Also being a fan of "Wu Xia" movies, I've seen the movie you quoted. "...kuai san fen" eh?
