Gooooood morning rest-of-the-world! How about giving me your opinions on this mystery crank. French certainly. To my inexperienced eye it looks like a TA but it's badged up as dural forge. The bottom bracket axle is a kind of half-cottered, half square arrangement. I have the pins but not the original cups. Can anyone put a date on it? And is it desirable? (just a bit too 'vintage' for my bikes).
I eagerly await your outpourings of knowledge and experience...

Are they alloy? They are old TA cranks as as I can tell. I think they would fetch a small fortune on ebay.

It looks a lot like a TA Criterium crank.

they are old style T.A. cranks (I think criterium).
contact Joel at above site he's forgotten more about TA than I'll ever know.

yes TA criterium later version (60s ?) looks like without pedal hole dust covers..
joel's site says it was only available for a few years
luckily you've got the most important parts

probably not likely to fetch a 'fortune' but not terribly common either

Early version, quite collectable. (to the Japanese!)

Outstanding advice, thank you. Yes Antoine, they're alloy. Marty, that site answered everything I need to know, except value. Ebay awaits, I guess...

dbakl, i wonder what makes you identify this crankset as an early version ?

joel metz does not mention any date estimates on his site and only lists a couple small changes,
the main ones being the dust covers and lack of logos, neither of which this set exhibits..

The half cottered, half not. A early 60s version that is pretty rare.

yes i'm aware of that, these features are unique to the 'Criterium' model, the only model we are discussing..
i meant to say that jeffieh's crankset appears to be a later version of this specific model.

Great post and cool evolutionary dead end! I have never seen cottered aluminum cranks before and never knew they existed, although I have seen Nervar cotterless steel cranks.

These WILL go for a tidy sum on eBay...I've seen it happen (but very few have ever been offered). Too bad that a few small parts are missing, that might kill the deal with a wealthy Japanese collector, but somebody will take them as-is, for sure.

That's an early 60s TA crank. "Dural Forge" is French for "Forged aluminum alloy." As mentioned, these are pretty popular with Japanese collectors lately.

Feel free to ignore this question if it is none of my business, but where did you come up with this?

jeffieh

Cool. Another of those 'dead thread resurrections'. And why not? Where did it come from? I can;t quite remember. I think it was off an old 60s JOCO I found at the dump a couple of years ago. Or it may have been on a crummy old 60s/70s Pat Hanlon frame I picked up around the same time...

Sorry, I didn't pay attention to the original post date. This Criterium (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250410404432&_trkparms=tab%3DWatching)sold on ebay yesterday.

...groan....

I had a pair of these, gave them away ten or twelve years ago. Don't ask me why.
