Rare Vintage Camel Legacy Thompson Satchel

Very Rare vintage Coach Thompson Legacy satchel/purse. Camel color. 100% leather. Solid made bag. There are no tears but needs cleaning. Please look at photos. The bag needs to be cleaned. I haven’t used in awhile and I honestly don’t know how to clean it. I’m scared of messing it up. #11373 ( does not have the gold coach emblem that hands from the handle.)
