I got in on this discussion a bit late. As mentioned, your lens is the genuine special mount that was used with the Canon 7 series, rather than the later TV version. In that later version, the thin metal circle at the rear of the lens is uncut, as is the rear glass element. The cutting of the metal was necessary to fit around the baffles inside the camera, and the uncut glass lowered the cost of production for Canon. The cut was only necessary so that the rangefinder cam could slide back and forth. The TV mounting didn't require this focusing. Most of the Leica conversions using the TV lens use a focusing cam on the outer mount, rather than one like the Canon setup, as far as I know.
With a box, even in a bit raggedy condition, your lens appears to be a very nice example. I would judge the value at $1000 to 1200 at the high end, if the comments made about the current impact of the M8 are correct. You were being ripped off by the camera store, regardless of the comments otherwise. An informed buyer should be willing to pay at least 30-40% of market value for used gear in this condition. He may or may not have had knowledge of the fact that it was an original, and not a 16mm TV mount. He should know, if he plans on staying in business, unless all he sells is digital. The additional large plate in your pics was used somehow in the TV mount for focusing. I've never seen on of the screw thread pices that you also illustrate.
Hopefully Peter Kitchingman will chime in on this with the last word. I know he'd be interested in pics of the box, as well, especially if it made mention of the TV mounting. For that matter, so would I, as I've no knowledge of that being done by Canon. I've never heard of a box offered with the TV lens, at all. The 16mm adapter with the small screw on cap is worth probably $50 by itself. If nothing else, it provides protection to the glass, for much less than the rare "real" back cap... they sell for well over $200.
A long post, but I hope it adds to your knowledge of the lens and its value.
