I have been watching the Accessories section on the official website for the S501 leather strap. I would like to buy one for my ALT1-ZT/51 as it's a softer strap than the vintage leather strap that the ZT/51 ships with. Unfortunately, I have not seen this new strap come up on the website. Does anyone know when, if at all, that strap will become available to purchase separately on the online store?

Thanks everyone for the help!
