Does anyone recognize this saddle post and adjuster nut, fastened to a Brown saddle? What bicycle does it go on?
I will take more photos and post them, today.Upon closer inspection of my Victor and Columbia post binders..... it's neither. Columbia used a V type wedge for expansion, no splits. Victor had two diametrically opposite splits. Yours looks like it could have three, maybe four splits, can't tell for sure from photo.
I will need to find my calipersIt is interesting that these collet style seat-post binders were around so early. Great reference materials above. Hawthorne with their version in 1937(I believe one year) that accepted only a 5/8" post came and went quickly and perhaps the last bike using one? It may have been abandoned over time because of higher costs? It seems the better mousetrap than a pinch bolt through a slotted seat tube as it was much stronger and eliminated the structural forces delivered by a rider loading this area/junction of the frame. What is the OD of your collet @GiovanniLiCalsi ??
