Peugeot triathlon help needed

[Vintageroadb]

Just bought this Peugeot triathlon and after the smash with my harrier was to bad to fix! Was an eBay job so more pictures on arrival but does anybody have any information on this bike? Been told all original parts are still on it bar the wheels! In my eyes was a bargain as it's in working condition.
Also looking for some white walled tyres, well made at a decent price! Does anybody recommend a site online?

Thanks
