Thread: Repair or replace?

Hard to really tell on my phone but the bottom one looks like ivory and doesn't seem to have a collar, can't tell about the top one. I have nothing to offer as far as fixing them but as for identifying ivory, it is generally much thinner than bone and bone usually has visible pores where ivory doesn't. Also ivory will have Schregar lines which is more pronounced on some scales than others. I agree with Pithor about leaving them be unless they become problematic. I have a CV Heljestrand with ivory scales and one is chipped with a small crack but it doesn't really bother me and I would likely make it worse if I tried to fix it. Also one of my ivory John Barber pair has a crack similar to yours and I'll leave it be unless it worsens which it doesn't seem to be doing. You can see the Schregar lines pretty well in this pic too. Best of luck with whatever you choose to do.
