That sounds like a bumper Christmas for you Johnny, new toys to play with. That's me the only one without a Kiev now.
I've resisted the temptation to buy anything apart from more light seal foam.
After lots of fiddling, I've now got one fully working Tessar with clean optics and oil free blades. I had to reassemble it god knows how many times because the diaphragm mechanism kept falling to pieces, and then again to get the focus right but the distance marks on the lens seem accurate now. Hypothetically, if I take the hours I spent on it at the minimum wage, I could probably have bought three!
One more to do, the Zebra; the diaphragm is cleaned up but I can't coax the lens barrel back into the focus ring on this one.
I'm off work until the 4th but at the moment, I'm too lazy to drag myself out of the house.
