Subject: [CR]French BB Thread and 70-mm Shell

I'm pretty new to this vintage bicycling world and have a question about bottom bracket thread standards. I put a bottom bracket on Ebay:


The bottom bracket came as a unit from a bike that appeared to have a checkered past. It was rattle-can repainted and had a mix of campy and suntour parts.

I got a Ebay message informing me that the 70-SS-120 spindle should not be with the 35x1 cups, since a french bottom bracket shell should be 68-mm.

My first question is: How rigidly was the shell width standard followed?

My second question is: Should I pull my auction?
