I just received a Bronica MF finder S ( the stove pipe) from KEH. They listed it as bargain and it is in very good condition. Except for the dirt specks on the inside of the bottom glass. Does any one have any experience with removing this glass. There are several parts to the bottom of the finder,The contacts for the metering and under that two metal bars that may be the clamps for the glass it self. Any suggestions would be appreciated
