circassian

I recently bought a very rare antique circassian saddle, don't know how old it is, my guess, it's from mid 19th century. My knowledge about antique leather saddles amount to nothing. The saddle is in bad condition, desperately needs cleaning and restoration. I am looking for someone who can clean and restore the saddle or some advise how and where to get help. I live in Rhode Island - US. Any help would be greatly appreciated.
