The Levi's 503B reproduction is a faithful recreation of the 1950s 501xx. At the time of production, Levi's was unable to obtain permission to use the 501xx designation, so it was named 503B. Like the 1950s 501xx, it faithfully reproduces details such as the button fly, red selvedge, leather patch, and big "E." Japanese reproduction models are becoming increasingly rare, so why not take this opportunity to purchase one? - Brand: Levi's - Model: 503B - Sizes: 30-36 - Style: Straight Denim Thank you for viewing.
