Exactly. It would have nothing to do with The Tramp costume assembled in LA on his first days with Sennett.
It looks to me like they have assembled bits and pieces of purported Bille Ritchie costumes and are packaging it as this, meaning the cane and the shoes do not belong. That cane has been auctioned serveral times for little money.
Also, if memory serves, the original Ritchie costume was sold back in the 80s, in London, right from the family and came with letters.
