Help Wanted with image enhancement

I have a ceramic pot which has an indistinct makers mark on the bottom. I have scanned it and tried messing with image adjustments, but have failed to enhance the mark to a point where it is reasonable.

If anyone out there feels they have time to give it a whirl pleas PM me and I will send a copy of the image.

It is currently 600dpi full colour jpg but if other format is wanted I can re-scan. I use X8 Student edition Photo Paint but am not experienced with the software and age 65 amd stuggling a bit with it.

Attached is cropped area.
