getting my first euro from africa soon. i was in the taxidermist's shop just a little bit ago getting my back skins/rugs, and he still has some work to do on the euros.

my question is:
on my wildebeest euro, on the back, the horns are flaking and turning brown near the base from the boiling i'm assuming. the Taxi said it was usual to expect this from africa.

is there something a taxidermist usually does to hide/fix this? or is it just something i have to accept?

i'm not sure what to expect here.
thank you
