General Information
These are the "Standard" reach version of the brake calipers.  CB-3600 is the "short" reach version.
Later model with "hidden" springs.  SSP calipers were all marked Superbe, not Superbe Pro.
When the brakes were paired with levers, the set took on model numbers CB-3000 and CB-2000 depending on lever and brake combinations.

NOTE:  If they are engraved 4000 on the back side they are short reach.  If they engraved 4700 on the back side they are long reach (CB-4000/4100 w/Levers)                  Basically the number is the low-end reach in mm x 100.

The Attachment bolt was available in a cone (or domed) shaped 10mm wrench style or with the addition of the recessed Allen key option as shown above.

SunTour (Maeda)

SunTour derailleurs have a two-letter date code. On rear derailleurs the code is stamped on the back side of the inner parallel arm. On front derailleurs it is stamped on the back side of the inner cage.

The first letter represents the year. Larry Osborn and I believe O (Oh) is 1972, V is 1979 and A is 1984. As with Shimano, the second letter is the month code, where A is January and L is December.

The earliest Suntour derailleur I have found with a code is marked OF. A rear derailleur marked OD (corresponding to April of 72) was reported by Leighton Walter. I have a bike that dates from between 1970 to 1972 that has the original SunTour derailleurs. These derailleurs do not have date codes on them, so I believe the coding started sometime between 1970 and April of 1972.
