Levi Strauss 508 W30 L32 unusual no riveting slash pockets

Hello and thanks for looking what we have here is a bit of an oddity these are 508’s unlike any other I’ve seen before. They must be a special edition version with blue tag and silver Levi’s logo. Excellently made with straight and tight stitching, and surprisingly have no rivets, and made with heavyweight denim. They are new without tags never worn. They are a combination of slim/straight pattern with leg cuffs measuring about 7 inches, and a seat rise of about 11 inches. If you have any questions please msg me Thanks Jr
