These 36 molds seem to be on the scarce side and when I've seen them, they demand a pretty hefty price as compared to other used Lyman molds . . not as frequently run across as other calibers I should say.
I've never used them in my .36 but would certainly try them if I could. With the interest there is in them, I'm really surprised that someone hasn't contacted a good mold company like Al at NOE or Accurate to see if they would be interested in possibly machining them and then a "group buy" put together on them.
