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.

Here's Canon's Online Camera Museum, a great source of info for old cameras/lenses
I've got a 50/095 that I converted myself to Leica M, from the custom Canon mount. I paid about US$760 a year ago for an unconverted lens. I've never seen it go for this low since.
Taking a shot of the rear with the lens cap off will confirm that it is not a TV mount. I've a attached a shot of the rear of my lens. The brass coloured piece where the lens has been lopped off is for the rangefinder focusing (my unconverted to Leica M mount, lens photo attached). If you have this tab, your lens is the more valuable NON TV lens. You will note the parts at the right of the picture that were removed from my lens prior to taking this photo.

I want to thank all of you for your help. I listed the lens on eBay and it is now listed at double what either of the camera shops would have paid me.
I was wondering if the people who run this web site and very informative board accept pay pal donations? I am not a rich man but would love to insure that it keeps running.

That one is pretty nice, but I think it was near mint rather than mint. I am really picky, but on the larger pictures I could see marks on the barrel knurling and dirt or oxidation on the rear mount area. Also, the hood had some marks and there was no box or rear cap (unlike the one from quixotic). Still a decent deal considering you are getting the elusive original hood and UV filter, if only for the sake of completeness.
Almost seems a shame to take such great examples and "cannibalize" them for M-mount conversion. Some of the conversions I have seen are a bit "ghetto" in that there is extensive grinding/sanding of the bayonet ring/flange, as well as cutting and drilling of that area. I wonder if anyone does a nice, clean "reversible" conversion by removing that bayonet flange and using the existing screw holes to install the M-mount?

Watch that step!
Yes, I agree that way too many of these are being cannibalized for use on M mount Leica`s (not the right way to go) this lens was made for the Canon 7 and 7s and the work I`ve seen shot with the combo in the right hands is amazing 
The ex-owner who posted here about that lens, had made the deal with me for it and renigged it out on me, for less than a $200 profit (not a very honorable thing to do) - the prices of these lenses are quite inflated now (people seem to forget that less than 8 months ago these were selling for $500 or less) and not alot of people wanted them.....
Many will bast*rdize these lenses with the shoddy M mount conversions
(I know someone who does a reverseable conversion, but I`m not at liberty to share this information at this time - and you STILL have to cut the lens protector tabs off the back of the lens so it clears the inside of the Leica M6) these lenses will be worth alot more money in the future in their original Canon 7 mount as in the conversions and many will also find that the conversions often DON`T always work as well with their M Leica afterall
I`m still looking for one of these, but I`m not going to pay an outragous market price, some other professionals here have also agreed that this lens should be in the $650 to $700 bracket and I think these mad prices over $1,000 for just a lens is just silly, you can find good combos of this lens with a Canon 7 or 7s for that amount and that`s just the way I expect to find one JMO

The diameter of the breech-lock flange is larger than an M mount, so the screw holes aren't in the right place. They're too far outside where the M mount needs to attach.
However, a neatly done conversion should still be reversible, because once the breech-lock flange was reinstalled, it would cover up the holes drilled for attaching the M mount.
