For me -& I'm sure for Jacques, too- your frame is not good for riding anymore: the small lips under the top tube near the headset lug is a sign of weakness; the tube could break at the first push. Or after 1000km... But I'll ask for its birth certificate. That sounds pretty depressing. I thought these bands weren't so fatal, but I was obviously wrong. Thank you for asking for a birth certificate

There is not much than a try. Without warranty... Start by assessing the bends. Take a straight lath of a bit less than the lenght of the horizontal tube (that you can put on the tube) Put it on top of the horizontal tube and take note of how many mm of play you have next to the steering tube THe diagonal tube must also be bent, so do the same with it. Then try to staighten it. Dismantle everything and replace the cups of the steering by a less valuable one. This serves the purpose of protecting the steering tube. Replace the bottom bracket by one of the same thread that you could dispose of (could be that the bearing will be damaged. Then fit a crankset with both pedals pointing in the same direction Take a strong steel rod that passes through the steering and that would be longer (down) Sit on the ground with your 2 feets on the pedals, headset pointing to you Take the rod and pull it toward you. You can be lucky. ... or not. If you didn't got my explanation, let me know and I"ll try to find time for a little drawing I understood your idea perfectly. I will definitely try to straighten it. I hope I'm lucky. I will share photos of what will happen soon. Thank you again

They are pretty small but its there .. I'm on vacation right now, but as soon as I get home I'll try to straighten the frame, as you described in the previous comment. I will keep you in touch.

My serial number is 3774 and based on other comments and serial numbers, I think the frame is from around 1969. May 3rd 1968 (sorry for delay) I was wrong: Jacques is not agree with me about the shock on the top tube. Could you please take a more detailed picture?

Could you please take a more detailed picture? the underside of the downtube will reveal the best if there has been a shock - so that the crucial area to picture and a side pic with the bike on an horizontal surface a straight ruler on the top tube will also help to asess its true the pic provided until now may be misleading !

AlainM, je te rappelle la parole sacrée du vénéré grand maître : "Tu peux y aller. C'est pas du nougat! " Sorry Llminoll. You can't translate this. There are some bents that you can undo. I have from time to time bent forks. Bent frame is less common. However we are to remmember the fact that good frame maker used to straighten their production after the welding process and realign everything. Jacques, one of the few master was not using a full jig to braze the frames when using luggs. He was not using nails to keep the luggs aligned on the tubes. with your finger, you can verify this. To verify the alignement of 2 tubes, he used his eye. Pointing a point far away and ensuring the good alignement. And reworking the complete frame later on, on a very large, massive, steel bench. If my memory is correct, this one was purchased together with a bunch of tube sets by a young guy (younger than me) who was planning to establish himself. I don't think he managed to do it. Jacques is a colossus. Taller and stronger than Hercules, in matter of seconds, bare handed, he was bending back frames, brakes, derailleurs ... Very impressive

Bonjour , pour continuer sur les plumes sport , je viens de récupérer un vélo qui aurait appartenu à Cyrille Guimard selon le vendeur. Son cousin courrait en amateur au sein du club cycliste de saint Herblain prés de Nantes ( ussh ). Le club aurait récupéré les cadres de cyrille guimard et son cousin en aurait racheté un . Le cousin l'a ensuite donné au vendeur en lui disant que le vélo avait été fait en belgique spécialement. Bref en postant sur les tontons velos j'ai eu la piste des velos sport plume , car la typo et l'emplacement du marquage y ressemblerait et les raccords avec des trous ressemblant bigrement au velo page 24 du sujet des plumes.

Après avoir réexaminé mon plume sport avec marquage sans les lettres PS, puis je demander si le collier d’arrêt des gaines dérailleur (près du raccord de direction) est fixé à travers un anneau brasé au cadre?

Non, il n'y en a pas ,ce cadre est prévu pour un collier rapporté.

J'ai vu cela. Collier porte manette bridouillé ...
Là ou le collier est serré par un écrou/boulon, Plume Sport brasait un petit anneau sous le tube et ce boulon passe au travers.
Perso, je reste très sceptique sur l'identification.
