Nikon BCB-II Flash Unit for Nikon S Cameras

The Nikon BCB-II is a vintage flash unit designed for Nikon S and late-production “synced” M rangefinder cameras. Built for dual contact flash sockets, it offers a classic accessory solution for early Nikon shooters and collectors. This set includes original components along with carefully restored parts for continued usability.

Includes:

• Main flash unit - cosmetic crack on top of housing (does not affect function)

• 6" reflector - accepts Edison-size flashbulbs

• 5" reflector - accepts #25-size flashbulbs

• Battery/capacitor insert - includes original capacitor, 25V battery not included (out of production), untested

• Penlight battery insert - modern AAs do not fit, untested but expected to work with correct vintage batteries

• Handle extension - fits 3x D-cell batteries, tested and working

• Camera bracket - rubber padding replaced with custom 3D-printed TPU part

• Sync cord - rebuilt with 3D-printed SLA parts to replace degraded moldings

• Instruction manual - original

Please note some components remain untested due to battery compatibility. Camera and flash bulb not included, only shown for photo purposes.
