Thanks for the information, Chombi! I am honestly not that concerned with keeping it all-French and period correct because this is just a commuter bike for me (albeit one that I love and cherish and think is gorgeous). I just took a quick look around eBay and those models, with shipping, aren't going to come to less than a hundred bones, while that VO sprung saddle is $65, free shipping. Luckily, the good thing about the saddle is I can swap it out for one of the lovely swoopy Ideale saddles later if I change my mind without having ruined the bike as a whole.
