This incident provides another little data point. A year or two back I was interested in a different focus screen for my SQ-A. I saw screens go for nearly $60 on ePrey and people asking $35 to $40 for cranks. I was tempted to buy another body (typically less than $100) just for parts -- now here's another little widget I'd have backup for! I now inadvertently do have a "parts" body, as its internal shutter release mechanics are stuffed.
With the detail in the new pics it wuld be really easy to fabricate from that there aluminium stuff.
Why do you folk have to add them thar extry letters to all them words?
Self timer lever sounds like a good idear IF the hole was smaller to begin with, if larger it's difficult to fab up a part of a hole. Fill it with JB Weld & drill/file it out I guess.
