This is the Canada made model, black, serial #2370855.
It works absolutely flawlessly. Focus is smooth, aperture stop clicks are great. Glass is perfect. There is NO fungus, but a small amount of dust inside, but very small amount.
The outside black is rubbed in areas from use, but works perfectly. Has built in lens hood, does not include front or rear caps.
I'm selling for $550 and I'll pay shipping CONUS and PayPal fees.
