Yes, Mr DQ, the glass looked like racoons had danced the Swan Lake ballet on it. I considered trying some Cerium Oxide to polish the front cell (uncoated). I don't remember exactly what made me drop that idea...I think I found something else wrong I think the rear cell had a problem too.
I couldn't get the leader of a roll of film to stay in the camera on (WPPD) Pinhole Day & ran out daylight so I spent time relocating the aperture to get rid the 'porthole' I had on the first implementation. Zippy was added in response to my wife sneering at the pinheads taking blurry pictures. I guess she's from the F32/F64 school. :O)
