this will come of use for gauging the market value and also ebay (completed listings).
I'm not so familiar with canon rangefinder gear but sometimes some accessories are worth quite a bit.
I was going to suggest this as well. its a good site for getting an idea of prices. You will see links to sections on Canon lenses and Canon bodies (these are sometimes listed as Canon RF - rangefinder or Canon LTM - which means Leica Thread Mount referring to the type of lens attachment). Go into each of these sections to find the equipment you have and then compare prices.
Be aware though that with classic cameras and accessories its all about two things. (1) Rarity and (2) condition. There can be BIG differences in price between equipment that is in mint condition and equipment that is merely in good condition. As most equipment has been used by someone mostly its only in good condition
at best.
Another factor of importance is the potential need for equipment to be cleaned, lubricated and adjusted (CLA'd). Potential purchasers will factor that into the amount they are willing to offer unless iron clad guarantees can be offered as to how well it is functioning. Old mechanical cameras almost always need servicing / CLA'ing to get them working properly, as mechanical timing mechanisms are delicate and lubricants dry out. Old lenses often become cloudy (or worse still get fungus on glass) if not kept in perfect conditions.
Its best to have an experienced user (if not a technician) look over gear and to note wwhat they recommend. otyherwise sell the gear with the words "as is" in the advert. In this event people will expect problems and will offer you less. But at least there can be no disputes over condition of the equipment.
Finally if you advertise on line make sure you have clear pictures of each object for sale. And make sure that the camera and lenses in particular are photographed several times from various angles so people can see exactly how they look. Non pro sellers too often post a blurry photo taken from too far distant to be able to tell a damn thing about the condition of something they are selling. Speaking personally I always move right on to the next ad when this happens.
When I sell, I rarely sell on line. If you live in a good sized city then it may be an option to find a camera store that is willing to sell on consignment for you. Usually they will take between 12% and 20% of the selling price. But as you can usually ask more than you could online (unless you have something very rare) then its not a bad option. But you need to trust them. I have a good one in my city and I have dealt with them for perhaps 20 years as sometimes selling on line is just too much of a pain.
Apart from all of that it sounds as if you are a lucky man. This looks like a great collection of nice equipment.
