Hasselblad Macro Flash Bracket 450-60 Medium format camera

This macro flash bracket is, in my opinion, in good usable condition and seems to have been barely used or not used at all. The flash bracket includes (already mounted on the bracket) an adapter for 60 mm diameter lenses (B60?), with an extra adapter for 50 mm diameter lenses (B50?), and the original user manual. I no longer own a Hasselblad and haven’t been able to test it.
