There is a new Kickstarter project for a Petzvar 120mm f/4 lens with central leaf shutter for Hasselblad 500 cameras. This is a second generation lens based on the first Petzvar 120mm f/3.8 version:
"The 2nd generation Petzvar shares the same optical design as the 1st but this time has been integrated with a Hasselblad Synchro-Compur leaf shutter mount, harvested from the famous C-generation lenses. Well researched readers will be aware that Hasselblad C lenses were built in very large numbers and to a very high quality from 1957 until 1970. With the cleaning, lubrication and adjustment (CLA) service, that each 2nd generation Petzvar will include as part of the build process, these lenses will continue to offer many decades more of excellent service."
