Hi,

I'm replacing the cord on the opthalmoscope illustrated.

The strain relief at the bottom of the handle, left in the photo,
was released by a pair of clips on a plastic ring. The quick-connect
holding the head was locked by a 2.2 mm socket setscrew in the upper
thumb ring. Finding a 1.2 mm hex wrench wasn't too difficult.

Now I'm snagged to release the handle from the internal structure.
Appears the handle is a tube. In the photo the outer handle should
release to the left; inner part to the right. What holds these
together?

Thanks, ... Peter E.
