Could someone tell me how to identify the model of this Motobecane Mixte and provide more value and background information?

Images are here since I cannot post attachments or links yet. The domain is ibb.co and then slash and then the codes. Let me know if I need to take photos of other parts of the bike.

I'm also missing the front brakes and the dia-compe calipers I have have the middle screw being either too long or too short. Are the center bolts changeable?
