I've stumbled across my Dad's 70's Rollei 35 and found two things;

1. There was film in it - more on that later.

2. There was a battery in it. 

The battery (of course) is dead and has vomited rancid chemicals onto the terminal and stripped the plating off. I've swabbed the worst of the gunge off the metal, popped a battery in and the light meter needle moves when you point it at the window so all good so far. 

My question is this, is there a Top Tip for brightening up the terminal metal?

It doesn't look like a good electrical contact and I can't imagine it working for long.

Lightly "tinning" it with solder??

I'd clean the metal tab with Paraffin or Methylated Spirits or IPA if you have any.

Then a bit of fine grit Emery Cloth or paper.

Finally a very light coating of Vaseline (electrically conductive and provides a barrier to prevent oxidisation)

That will get you a good electrical connection.

If you have soldering kit then a bit of Solder won't hurt but it will oxidise just as quickly as the base metal.

Nice find.what specifically have you got?

More on the film? What is it. Kodachrome you have no chance of getting the photos because no one i am aware of has come up witha viable alternative to kodaks binned system.

Black and white should be retrievable. Colour i have had mixed success with but can be okay.

Also before you go wild. And you have found out which version it is. Read the instructions, i vaguely recall a flaw in the design regarding order of doing things that can jam the shutter.

Konica Centuria C-41.

Everything jams the shutter, it's interlocked to every part on the camera!

Well yes i rather meant something a little more permanently jammed.

 

Ie asjust the aperture without he lens extended fully.

Might be misremembering.

My old cameras tend to be the decades prior. I like something i can fix rather than brick.

Nice cameras though.

Brick?

Then a bit of fine grit Emery Cloth or paper.

What might be easier to use would be one of those hard blue or red erasers used for ink on paper instead of paper - they have some abrasive qualities, and being fairly hard would be easier to work than small bits of abrasive paper. Useful for other applications as well.

brick: create an irreparable paperweight.

I am pretty comfortable fixing the previous generations of cameras with lighter fluid. But something that complex scares me.

The blue rubber is a good idea. 

To be honest though I have always just attacked my cameras with a scalpel and they've worked perfectly.
