Oh - no, it should still be sharp. As far as I can see, there is a ^ the second time, unless we're talking about something else...? I've taken the piece from the earliest publication (Edward Jones) which doesn't sharpen the c's in that bar, but we play it # these days.

I can't see why there were 16th and 32nd notes at any time. They never have appeared when I've processed it ...
