Not much hope with that one in my opinion.
You can use a fast-fourier-transform (FFT) and since you are using Windows you might try the gimp_gmic_qt plugin http://www.gmic.eu which has a version in the frequencies section.
Works like this: https://i.imgur.com/xB45nOZ.mp4 to give this
The problem with this type of image is, try and sharpen the result and the pattern is restored.
Is that your own scan ? Part of a larger image ? Ofnuts has a procedure where you carefully scan from different directions and "difference" layers. Not easy to do.
