In Edith Mannoni's book on Schneider, the "candy cane" is described as "a tiny cylinder of blue, white and red striped glass".
The cane in the item being considered has a distinct blue line spiraling around, but connecting at the ends of the blue that can be seen as more of a "shadow". That suggests this cane is formed partly of clear glass with the colour showing through. Is that what the Schneider cane really looks like? I have no idea!
Also the cane is "lobed", as would often be expected when working with a section of filgrana twist - but does that mean it is not a "cylinder" as stated by Mannoni?
Not sure if that helps at all.
