Hi there ,
I can not tell if you have mildew or mold from these photos , a sniff test could tell you . From the photos I see Lots of color loss , will need color restoration , some missing top skin that will need recolored ,resins need redone as well. In the right hands this could be greatly improved. I’d make sure whom ever you entrust it’s restoration is trusted and experienced.
it’s still a sweet boldie imo, and black box calf usually restores beautifully.
I hope this helped ?
All the best
Doc
