I have 2 cameras extensively serviced now by Wilco Jansen, an experienced camera repair man in The Netherlands.
He is a Hasselblad specialist since 1967 and gets orders from Hasselblad itself also.

He repaired my Konica III rangefinder (sticky blades & damaged shutter) and did an extensive overhaul of my Hasselblad SWC from 1964. He also does analogue cameras like Canon and Nikon.

I can recommend him. His website.
