Those 8514 are .fon files and belong to the Windows system, Raster fonts I think used in terminals.
Same result as Blighty the Old_Street_Signs.ttf does not show up in Gimp 2.10 (Linux or Win10)
Try the attached, I have run it through FontForge, fixed a couple of things but still not 100%
It is renamed internally so will show in the font list as Old-Street-Signs-Bold. Should be no conflicts with the old file.
The font only has capitals (upper and lower case are identical) and nothing else other than the space character and the copyright symbol. Anything else will use the default font (I think)
edit: If the attached does not work, it will be a language issue, works in English but not in..(put your language here)
Reworked the file, now as an otf:
Looks like this in Gimp 2.10/Win10 : https://i.imgur.com/rktDxZk.jpg Compared to the sample file that comes in the zip.
