Ilex Acme shutters use hard rubber shutter blades. Solvents such as Naphtha (lighter fluid) and Lacquer Thinner will destroy the shutter. I can do a CLA for $70 + shipping if you are interested. A functional View I or II should go for around $250 without lens. The Paragon is not a real popular lens and should go for around $175 in a working shutter.

The Acme is not a complicated shutter. Your #3 will be similar to but may be a steep learning curve if you haven't serviced a shutter before. Take a picture before and after removing each part. Little thin brass spacers stick to the part or case only to fall off later.
