Anyone else here into cold cameras/ film photography?

[Telecolor 3007]

I do like to take pictures with film camera. If it wasn't for the film some of the memories would have had been lost. But it's the fun and thrill of it too - to not be albe to see the image seconds after you took it and so to do the best to get it good, having a camera that dosen't swallows much current or even dosen't need batteries (oh, but you need an exponometer), beeing able to use cameras that are half a century old or even older and get nice results, you can change the "sensor" from inside the camera.
But why "cold camera"?
I will take adavantage of this topic (therad) and ask where I can find an adaptor ring that allows me to use a Silver Oxide (1.55 Volts) battery in stad of the old 1.35 Volts Mercury battery... so it's a ring that lowers the voltage. I need it for the internal exponometer of a "Minolta" camera.

@ Olorin67 : maybe you meant that the "Ansco" camera is from 1947-1948, not 1847-1848.
