Found these roundballs today.

Found these roundballs at a Rev.site today. I put the quarter for size comparison, wondering if any one out there could give me some info on caliber and timeframe. Know thats asking a lot from a pic, but im sure someone on here knows about roundballs.

I use a micrometer to measure, get a cheap caliper.big 'un could be a 75 cal. if it is flattened, otherwise it appears too bigly

If I found them here I would say that the larger are British (75 cal) and the smaller is French (69 cal).

Just measure them if they are still round, the size is the caliber. Can't really tell anything from the pictures. If you weigh them the caliber may be able to be determined as well.
