Hi guys, I've got this

very old, unclear image of hand drawn, (the original got lost), any suggestion as to how I could restore, clean up and/or sharpen would be gratefully appreciated - in Peace RJKD

You can try duplicating the image and applying Image Mode>Multiply.
Doing this will darken the lines.
Duplicating this layer and playing with the layers opacity, can refine it a bit more.
Using, Color>Curves can also help to improve the lines visibility.

I liked the lines, but couldn't get the faint ones to stand out, so I just had fun.

Beautiful animicule, however, I think I'm asking to much to restore, it's a scan of a photo of 34yr old sketch, the original got lost along the way - in Peace RJKD

Duplicate layer.
Color to alpha - white.
Duplicate that layer until all the detail shows up
You could clean this up further by removing yellow/orange.

I tried using threshold to do this, but it didn't work. Any hints why?

I am not sure why threshold did not help much.
I am wondering if changing the "color set" from RGB to something with less colors
might help

Used levels and got black (luminosity masking), changed to blue channel and more
details appeared. xcf file too large to post. you could probably clean this up a bit and
add from the original by hand.
