I need some information on a 1988 Peugeot Chorus model built with Reynolds
753 tubing.

Apparently this model was only made in 1988. It came with Campy Chorus
components.

I'm trying to find the original width for the rear dropouts, 126mm or
130mm?

The current width is 125mm but the owner was using it as a fixie and
someone may have narrowed the dropouts.

Also did this come with 7 or 8 speeds?

I've found references to this model on the internet and a similar Galiber
model made with 531SL but no specs.

The frame has English threads in the headset and BB but metric sized
tubing - 26mm and 28mm main tubes and a 32mm head tube.
