I recently came into possession of a Voigtländer VAG with a Rollex film back. I hope this is the correct forum. It is a plate camera but as it i outfitted with the Rollex I intend to use 120 film for now. It is in excellent — but aged — condition. It is a bit dusty. The ground glass looks fine (there is a dent on the rim). The shutter fires and the bellows are in great shape. No light leaks that I could see. It appears to work — the shutter at least. We shall see what photos come of it.  
  
But I have some noob questions — 

* How might I clean it? 
* What is okay and not okay to use?
* Is compressed air ok to use? 
* Isopropyl alcohol? Or just soapy water? Or is that bad? The lettering and number is engraved but the white paint is fading or rubbed away — I do not want to damage that any further.
* There is white dust inside the bellows on the backside of the shutter -- what is it and how to remove. Photo attached.
* The mirror on the viewfinder is spitted and pitted can that be replaced or cleaned?
* Are there any parts that need lubrication? It slides a bit stiffly along the rails. But does move.
* Do I need to do anything to the bellows to keep them in pristine condition?
* I would really like to clean and polish the chrome parts so they shine again. No real rust but they are dull. 
* How would I deal with rust of there is any? 

Finally — the shutter cable release that came with it worked for two presses and then gave up the ghost. I was not surprised as the fabric is almost 100 years old.   


* Can I use a modern cable release? 
* Is the threading the same? (I guess I could get one and find out.) 
* Do you have any suggestions for a cable release for this old of a camera?

Thank you in advance for dealing with and understaffing my ignorance. This is a new hobby and I wish to learn by trying and not just dropping it off to a camera repair shop and paying to have it made like new. For a Voigtländer it is not that rare or expensive. So good to learn on. I have not found a manual online -- but have seen one for the Avus which is similar but not 100% -- so I will be posting some operational questions as well separately.  
  
On that note — any suggestion for film? I plan on shooting architecture mostly while I learn the ins and outs. And perhaps some portraits of my daughters.  
  
  
Thank you.
