Hello,
Ok, back to this slow project for a minute. Since this is mainly cardboard and nails, there is really not much to disassemble without destroying it. The good thing is that since this is mainly cardboard and nails, there is not much to disassemble anyways.
After the simple shutter mechanism was brought back to life, a good clean was in order. Both viewfinders were cleaned inside and out the best I could. Far from perfect but they do their job. The outside covering (not sure if some sort of leatherette or what) was carefully cleaned with 409 household cleaner. I had no idea how it would react so I went very gently. It was clean but the top was dull, so I did a bit of "Bling" experiment and added a touch of Armor All on the top only. The faceplate is very delicate. The first touch of mild cleanser and the vertical lines suffered. So it was left alone.
This can use 120 film. However, from the little I've searched, the little red window does not align with anything currently available. So I'm using the paper backing of used film (no film) to calibrate how many turns of the knob are required. That's where we are now. It will still be a while but I hope I can eventually run a roll thru it.
Thanks,
Ismael
