That is how I feel about restoring my dad's 1949 Leica IIIC. It is a link to him and to his prized camera with which he took family photos and traveled the world. The 50mm Summitar is pristine. Don Goldberg in Wisconsin cleaned and overhauled the body. Indeed, we are caretakers, even though most people scoff at the concept.

Caretakers, yes, however only for certain items which are inherently durable enough to respond well to care and maintenance - lots of stuff isn't. An F2 is designed with regular maintenance in mind, so is a Leica. So are lots of other things, watches, clocks, automobiles, etc..
Sover Wong does a great job, I have a Soverised '71 F2 with the DP II finder, it's essentially a new camera. Meter, shutter, all are accurate and it's smoother & a bit quieter than my unrestored '79 F2A. I purchased the '71 5 or so years ago, neither I nor the seller knew it had been worked on. The database at Sover's site confirms it was done about three years before I found it, the seller got it at an estate sale.
The '79 F2A - black - is clean, shows little sign of use & the meter works, it's likely it just needs stale lubricants replaced, which I can do myself having the service manual. However, if it turns out to need parts (I really doubt it does) I'm up the creek. I've been dithering about this long enough that, had I got on SW's waiting list when I first got it, it'd be done by now. F2A was a gift, so if I pay ~$300 for a complete reconditioning, it's a bargain.
