A few days ago I asked for information on a NOS JPR seat post I'd bought. I thought I'd share what I'd learned since I found it very interesting: These seat posts were made by the firm of JP Routens, the famous French constucteur. The were also included in the short lived Huret gruppo.
By the way, I have one on E-bay ( item # 140009821797 ) and I'll post some photos on the Velo Orange blog in a few minutes.
Many thanks to those of you who provided information.
