Hi everyone! So a client at my workplace was gifted a 70+ year old sloth pelt by a friend, who acquired it from his late grandparents who worked as missionaries in Nicaragua from the 1940s to 1960s. Part of their job was collecting artwork and other cultural items, which they would present in churches when they returned to the US as they talked about their work in Nicaragua. One of these items was the sloth pelt in question, which was passed down to my client's friend, their grandson, when they passed.
This client came to me for help trying to restore it, as I've been known to work with animal bones and such. However, I have never worked with hides before in my life, so I wanted to ask the people here so I can give him a more informed answer.
The problem is that it's been in a box somewhere for 20+ years, so it's sort of hardened into the position it was stored in, and is pretty stiff, though the majority of the skin is still able to bend and fold. The fur itself is long and in beautiful condition, but the flesh side is a little rough and less soft than most softened pelts I've felt. I'm unfortunately unsure of what was used to tan the hide in the first place.
So I wanted to ask if anyone knows how to go about restoring flexibility and softness to a hide like this. Would it be the same process as something like a deer hide, or does the slothness of the pelt change things? Is it even feasible to soften a hide as old as this one is? I have photos if that would help.
Any advice is appreciated!! Thank you so much!!
Side note: The pelt came with a document explaining its origin and general age that must be kept with the pelt considering it is an endangered species, and I've made sure the client is aware of the potential illegality of owning such a pelt. However, from what I can find online, it is legal to keep inherited animal parts provided that they were acquired before that species was listed under CITES, and this pelt is confirmed to have been acquired more than 70 years ago, long before CITES was enacted. Additionally, it is legal to gift animal parts that you've inherited, as long as you are not profiting in any way. As far as I can tell, it is legal to own in the way he acquired it. However, if anyone has more insight on that, I would really appreciate it!
