Razor Repair

[bmilesmiles]

Sorry if this is the wrong place to post this kind of question. Please let me know if there is a more proper spot. I have a set of Thornhills that look like their previous owner tried to work on but ended up splitting the scales. I would like to have them fixed up but I do not know what is possible or probable to try to repair. Mostly the pins need to be a little tighter (I've been looking up how to do that myself but suggestions would be welcome too) but also as the pictures show the ivory scales are a bit worse for wear. How much can be done and who is good with ivory? Thanks.
