A rare piece of Japanese industrial heritage: the S.K.C. No.800 Size 3, manufactured by Osaka S.K.C. Lock Co., Ltd. — once one of Japan\'s foremost producers of heavy-duty security hardware. Originally engineered to secure traditional Kura (蔵) storehouses and industrial warehouses, this solid-metal padlock was built to last generations. The No.800 line is long discontinued, and surviving New Old Stock examples at this substantial 63mm shackle clearance are increasingly difficult to find. Comes with 3 original matching keys and the original vintage packaging.

Originally unused stock (New Old Stock / NOS). Tested and confirmed fully operational — the lock opens and closes smoothly with all 3 original keys. The body and keys exhibit a natural aged patina and slight oxidation from decades of storage; this is characteristic of authentic vintage hardware and does not affect function. The original packaging is included and shows wear consistent with long-term storage. Please review all high-resolution photos to judge the condition for yourself.
Important — Key Notice Key Duplication — Not Possible
This is a discontinued vintage lock. The key profile is no longer in active production, and duplicate keys cannot be made through standard locksmith services. The 3 keys included are the only keys that will ever exist for this lock. Please treat them with care — loss of all keys means the lock cannot be opened without forced entry.
Key Condition — Signs of Age
As New Old Stock items stored for decades, the keys show natural patina and light surface oxidation consistent with the lock body. This is purely cosmetic and does not affect their function. All 3 keys have been tested and operate the lock correctly. Please review the photos to observe the key condition for yourself.
Safety & Use Notice
- 01 Intended Use This padlock is designed for securing gates, doors, storage units, and similar applications. Do not use beyond its rated load capacity. Inspect the shackle and body before each use for signs of wear or damage.
- 02 Key Management Store all 3 keys in separate, secure locations. As duplicate keys cannot be made for this discontinued model, losing all keys renders the lock permanently inaccessible without forced entry. Consider labelling and tracking each key carefully.
- 03 Lubrication & Maintenance Apply a small amount of dry lubricant or lock oil to the keyway and shackle mechanism periodically to maintain smooth operation, particularly if used outdoors. Avoid WD-40 as a long-term lubricant — it can attract dust and degrade the mechanism over time.
- 04 Outdoor & Weather Exposure While this lock was built for heavy-duty use, prolonged exposure to rain or moisture may accelerate surface oxidation on the metal body and keys. If used outdoors, consider a lock cover or weatherproof housing to preserve its condition.
- 05 Collector & Display Use This item is also suitable for display as a piece of Japanese industrial heritage. If kept as a collectible, store in a dry environment away from direct sunlight to preserve the patina and prevent further oxidation.
- 06 Box / Packaging The original vintage packaging is included and shows wear consistent with decades of storage. It is part of the item\'s provenance and included as shown in the listing photos.
- 07 Warranty / Liability Sold AS IS / WITH ALL FAULTS to the extent permitted by law. As a vintage item, no manufacturer warranty applies. Buyer assumes all risks associated with use.
