There's a French supported spindle pictured in Abby Franquemont's Respect the Spindle, on page 16. I'd read in Selected Canadian Spinning Wheels that the spindles used in New France had no whorl. Now I have an idea what they would have looked like.
You're still wondering? Well, I recommend you look at Franquemont's book, but if you imagine one of the uprights under the handrail on a banister, you'd be close.
