I figured Timmy was talking about modern carbon film resistors which probably are less resistant to arcing than the old carbon comps. I doubt he would be as likely to look up the voltage rating on a period part as he would a modern replacement being considered.

It makes sense the old carbon comps would have better resilience against over voltage since there's a nice straight path between the terminals unlike some of the film resistors now that have a spiral which can potentially arc between adjacent tracks and or the terminals.
