Hi I need some help about identifying a vintage Peugeot bike.
I have read a lot of posts on forums and other resources over the net, but I cannot find the exact model...

These are the characteristics that may help you:

It is a city, maybe utility, bicycle.
The original color was purple, no chrome on the frame nor on the fork. Just some parts as the handlebar, headset, crankarms are chrome plated.
I am not sure about the decals cause I removed them before thinking about identifying the model of the bicycle, but for sure the head tube and seat tube decalls are not type III, nor type IV, nor type V "following this post:http://cyclespeugeot.com/ModelID.html". The most probable is to be type I.
The frame at first look is very common (like a PX10 I could say)
It has aztec type lugs.
The S/N is stamped on an aluminum plate on the underside of the bottom bracket shell.
It is composed by 7 number, no letters.
The first number is 2 so the frame has to be made on '72, wright?
The frame pump holders are lockated on the downtube.
It has an Atax stem with a handlebar as the one on this photo: http://www.flickr.com/photos/reefflo...n/photostream/
It has a rack toolbox exactly the same with that bike, but the bicycle frame is different (http://www.flickr.com/photos/reefflo...n/photostream/)
It has only one shifter lever attached on the right side of the top tube
The rear derailleur is a simplex prestige (maybe S001T)
It has no front derailleur.
The frewheel is an Atom 3-speed
It has 26" wheels with "650B Std 40-584 26*1 1/2" tires
It has chrome fenders and the bolt that holds the rear brake also supports the fender (the hole for that reason on the rear is drilled top-down)
The cable holders are all the same with the bicycle mentioned before. I can hardly see one on this photo, but I could not find another (http://www.flickr.com/photos/reefflo...n/photostream/).

Unfortunately, I have no photos of my bike...
Any advice could be very helpful, Thank you for your time!
