This sale is for one Mamiya U Camera Replacement Shutter Button NEW, original Mamiya part 210-998. Almost every example of these cameras found has a broken shutter button. This is an original replacement part and is not difficult to install. The top cover needs to get removed and then the keeper plate and old button can be removed for installation of the new part. The last two photos show the top cover removed with the old button being replaced.
