625PX - still available in small quantities here (Australia) at a price (US$7-10). Otherwise a CRIS adaptor for SR44's. Someone here in Melbourne was threatening to start producing a version of the adapter with a better diode - I must check. DON'T use the alkaline 625 equivalent. There is a Chinese (Excell, Exell?) silver oxide version but it is 1.5V, not 1.35V and throws the meter off by up to 3 stops (on an OM1).
675PX - accidentally picked up a couple the other day for a friend's Konica but you'd be lucky. Get the meter recalibrated for 1.5V silvers or a diode installed (see below).
If you want to use a Yashica Electro, the old 5.6V is unavailable but the camera is voltage flexible and works fine with 6V. www.yashicaguy.com for a great little $15 adapter with battery - 544 alkaline 6V.
There are also tricks with Minox 35's (and Rollei 35's?) but they escape my memory at present.
Junk cameras often have a mercury battery in them with a little life left in it. They last for a long, long time. Scavenge.
Get an appropriate diode fitted in the battery compartment wiring - better than retrimming the meter.

I collect a lot of camera gear, some stuff is very, very old, while others are only 10 to 30 years old. I have several mint camera that used the old style batteries which were discontinued because of their environmental hazards. A general question, does anyone know if there are batteries that have replaced the obsolete ones? Two batteries I know I could use are the ones similar to the Lithium 3 volt types. One camera uses a similar sized battery but 6 volts. Thanks for any suggestions. Good holidays to all, Gregory david Stempel FIREFRAMEi m a g i n g
