Like the title says - One Box O' Junk. The items that have glass of some sort have a green X on them. The empty petzval barrel is 2" wide on both ends. There is a tessar barrel, the lens boards are 4 1/2" square on one and two of them are 4 3/4" square. I was going to toss this stuff but possibly someone can use it for something. Price: Medium flat rate postage to me ($10.95 USA), PLUS a contribution thru Jim Galli for Haiti for these incredibly valuable items, or as they say on Ebay: Extremely RARE and VALUABLE !!!!!!. What you donate is up to you.
