for the mamiya "c" lenses it's the chrome ones with seikosha and the black ones with the newer seiko shutter. so it's probably the same with the press/universal/23 lenses. as I hear there are no parts for the seikosha shutters any more, but I have not met a seikosha shutter (and I down own quite some lenses with them) that could not be serviced.
