Fixing a weird hole in old french scales

[OrSh]

So i got this old razor for very cheap, the razor was all worn off from excessive honing and was basically dead, but the razor wasn't the point. It came on a very nice pair of an early french scales I wanted to use for an orphan early french razor.
The german razor was clearly not the original and obviously too short for them, so whoever owned it decided to make a custom spacer with a steel rod right above the bottom pivot..
Removing the razor and the spacer without causing any damage to the scales was one of the hardest removals I've ever done! Boy that steel rod was thick and tight but after putting a decent amount of time using a Dremel with a very thin disc I managed to remove the spacer with one small overheating damage to one of the holes (yes I have an jewelers saw and yes I wasn't thinking of it at that moment ).

Now I have a pair of good early scales but with two freaking holes in it. My first thought was using a silver steel rod and just make a flat pin on both sides, but I wasn't sure how "authentic" it would look. I've read that some members recommended using a horn dust to fill imperfections on scales but never really delve into it.
Would love to hear some thought or helpful tips on how I can decently repair it
