Hi peppy - the above are the names on the different wallets/styles. Check more details from atelier.naff : http://ateliernaff.blogspot.com/2005/09/balenciaga-motorcycle-style-reference.html
Oh mine, i haven't answer ur qns.....see my answers below :
- Real coin means Coin wallet
- Coin could be coin purse
As for the le compagnon & Ni compagnon means the long wallet but one of them is with the zip and the other doesn't have the zip.
I will check more info and revert as i used to have the pdf.file on the whole list of bbags and the style names (which may not be the updated ones since they don't forward any files nowadays).
