Mercury-Cell Battery Adaptor

A simple 'battery adaptor' to allow 4 LR44 batteries to be used in place of a (mercury, hence discontinued) PX-32 cell. The PX-32 has a voltage of 5.6v whilst the LR44 stack will produce 6v. For some cameras this is Ok (i.e. my Yashica Electro 35), for others, the over-voltage may affect the metering adversely.
