Facom recently discontinued production of all 56L series metric sizes......supply is limited to stock on hand. The 55A series or 57L series may be suitable alternatives. The 55/55A series has been around for 20+ years and is a deep offset wrench (70 degrees....I had to go back to the F96 catalog to confirm this). The 57L series is closer in offset (15 degrees) but considerably greater in length and may not be suitable for working in tight spaces.
