Interesting. Assuming this means anything at all:
It seems the lettering system ends at “F”. Maybe these are two separate hexadecimal numbers? (separated by the hyphen)
As I remember it plaintext can be converted in this way (though I don’t know much about it, so don’t know how it would work exactly), so these hexadecimal number pairs might actually be text?
000-04749, for intance, seems to simply be “GI”. I see 13 number-sets cycling, so maybe together it spells something out?
Doesn’t really seem to go anywhere following the method I’ve used, but there might still be something in there.
