C100 mk1 is the hole 10-32'' or 1/4? Thanks in advance

i bought this (1/4'' to 3/8'' adaptor). I try to screw it on the hole of the audio handle of the Canon C100. It doesnt work. I've heard that the hole needs a 10-32''. Any tips ? Thank you. Have a good day.

The thread should be a ¼" Whitworth thread (BSW). The thread on those adaptors looks a bit shallow and fine to be that? This looks more like it.

I used to own a C100MK1. If memory serves me correct, the thread hole on the handle was 1/4-20. On the bottom of the camera, the thread holes are 1/4-20 and 3/8-16. These are standard thread sizes found on most cameras sold here in the US.
