Greetings,

I have just posted to my technical information site, The Pumpkin, a descriptive article entitled "The Packard Ideal Shutter", available here:

http://doug.kerr.home.att.net/pumpkin/index.htm#PackardShutter

The article describes the shutter, its features, and its operation, and in an appendix gives a detailed illustrated discussion of the workings of its simple but ingenious mechanism.

I would certainly welcome any additions or corrections to, or comments on, to the information in the article.
