Ladies and gentlemen, we have ourselves a winn-ah....

Yes, indeed, the entire lot of "Mystery Cogs" is now winging its way westward courtesy of the USPS Priority Mail service. From henceforth and forever, David Snyder of Auburn, California shall be known to one and all who haunt this hallowed forum as an official "COG-KNOW-scenti" in good standing - he having correctly identified the manufacturer and model of those cog wheels as being apropos a SunTour Microlite freewheel. A hardy congratulations and a tip of my hat to you kind sir for being able to render a definitive reply in but a mere one hour and nine minutes from that point in time at which the original question of their origin was posted to the CR List membership at large.

And now for the post mortem....

Many an individual were quick to posit that the lot of "Mystery Cogs" were likely of SunTour origin. However, there were mixed opinions thereafter as to whether respondents thought that they might be suitable for use on an original Winner freewheel body versus a New Winner or perhaps even a later Microlite freewheel. Of course, not having a Winner, a New Winner, or a Microlite freewheel at hand such that I could make an actual comparison for myself (...although I have at one time or another in the past owned a Winner and New Winner but never a Microlite), this is what I managed to compile given both a quick review of those SunTour catalogs that I have in my collection (...years 1973, 1975, 1977, 1978, 1981, 1987, 1988, 1992, 1993, 1994, 1996, and 1998 plus other various pieces of dealer literature - gee, guess who needs to do a bit more scanning and posting to WoolJersey?) as well as helpful comments from those wise souls who took time to thoughtfully participate in the "COG-KNOW-scenti" contest:

1) The original Winner / Winner-S freewheel introduced in 1975 used a combination of two eight notch slip fit cogs and three threaded cogs, assuming a five speed configuration. With respect to those cogs which are slip fit, the steel versions are NOT of a polyvalent design, but rather, have a flat profile and use separate spacer rings for purposes of achieving proper separation. Alloy versions of same were polyvalent and did not use spacers - just like the ones seen among the grouping I presented for consideration in the "COG-KNOW-scenti" contest. Inasmuch as the early Winner / Winner-S freewheel body itself featured a stepped profile, the remaining threaded cogs used two different sizings - one "mid-sized" to accommodate the middle gears and another "small-sized" to accommodate the final outer cog (...which was duplexed in a six speed configuration).

2) The later New Winner freewheel also used a combination of slip fit and threaded individual cogs of a generally similar design to those seen in the original Winner / Winner-S. However, those cogs which were slip fit used a four notch interface in common with SunTour's Pro-Compe and Perfect series. In addition, the New Winner freewheel body eliminated the intermediate threaded step in favor of a single threading for all remaining cogs.

3) The Microlite freewheel was built around an unique for SunTour at that time alloy body having CR-MO steel precision ground ball races and was available in either a six or seven speed configuration. It too used a combination of slip fit and individually threaded cogs, however, in this case the "anodized super duralumin" cogs were always of a polyvalent design which obviated the need for separate spacer rings (...steel cogs never being an option on a Microlite - duh). These cogs also used an eight notch interface similar to the Winner / Winner-S freewheel. But unlike the original Winner / Winner-S, the Microlite had no intermediate threaded step (...just like the New Winner) as it used only a single threading size for those cogs which were actually threaded.

Given that there was absolutely no differentiation or graduation in thread sizing exhibited among the wide variation (...14 through 19 tooth) of cogs offered as part of the "COG-KNOW-scenti" contest, it logically follows that they were not intended for use with the early Winner / Winner-S freewheel with its stepped body design. And in consideration of the fact that the larger editions of those very same cogs all used an eight notch interference interface, they could not have been intended specifically for use with the second edition or New Winner freewheel which used a four notch interface. And that leaves the SunTour Microlite freewheel as the only remaining alternative for which ALL of those cogs would be perfectly suitable.

In a noble attempt to address a couple as of yet unanswered questions, not only to sate my own personal sense of curiosity but also for the benefit of all others who may eventually search the CR List archives seeking these very bits of arcane information, I would now like to solicit yet further input from the collective wealth of experience embodied in the general CR List membership:

1) Can someone out there answer with authority the question of whether or not the larger eight notch slip fit cogs produced specifically for use in conjunction with a SunTour Microlite freewheel will also work on the original Winner / Winner-S model in the one and two inside cog positions (...as I strongly suspect may be the case)? Information presented on page 4-14 of my Sutherland's Third edition having the corrective supplement issued August 1985 would seem to indicate that this is a conditional possibility, but I am looking for a "real world" confirmation one way or the other from someone who perhaps used to wrench at a shop and has first hand experience with this exact type of substitution.

2) While it is understood that the remaining threaded cogs from a Microlite could in no way could be used to "complete" a Winner / Winner-S freewheel to the extent that the latter's stepped body design precludes such a possibility, does anyone know whether the respective threadings themselves are wholly unique from those two earlier versions of freewheels or whether threaded Microlight cogs might be able to fit onto either the middle or outer threaded position of a Winner / Winner-S freewheel or even onto a New Winner freewheel? Again, the aforementioned Sutherland's manual is less than obvious on the matter, although it would appear to suggest limited compatibility under VERY specific circumstances. Again, input from an individual having actual experience in the matter would be greatly appreciated.

Anyone having helpful / useful information in this regard or who knows of any inaccuracies with respect to those descriptions provided above, is invited to share their input publicly as I would very much like to "get it right" for purposes of informational archiving.
