Focusing Lense is Off

After a night soak in lighter fluid and a application of WD-40 the focusing lens thread of the Isolette II came finally loose today using only my fingers and a fabric cloth. This will allow me to clean the lens and to properly set focus. Now I just need to figure out how to undo the other lenses for cleaning and cleaning of the shutter blades. The test roll is now being developed to get an idea of the lens performance and the bellow condition. It turns out that the model I got has the entry level lense (Agnar) and the entry level shutter (Proto).
