My suggestion is to wait. The Leica community develops all kinds of silly obsessions and I bet at some point in the future the bubbled M6 will become incredibly hip, dramatically appreciating in value. People will be digging their cameras in acid to get what you already have. Enjoy!
Ok a great idea, except the door also has attached the ISO dial, the pressure plate, and the electrical contacts necessary to make it work, so yes a simple job
Wasn't the bubbling finish initially deemed a flaw that people avoid, then later determined to make the model more collectible once it had been fixed in the manufacturing process?
I can't keep up with Leica quirks and variations that make one more desirable than another. All I know is buying a multi-kilobuck camera to have it sit on the shelf seems like a waste for a camera that many claim is built to withstand the rigors of photojournalism.
