I recently purchased two eiIght day ogee clocks at a regional. One was a Forestville and the other was a Welch. The weights I received (from the same person) were about 2.5 pounds each. I don't have any otherr eight day ogees for comparison, but these seem to be what I would expect for a 30 hour. All my other eight day brass clocks use 8 pound weights. However, it looks like an 8 pound weight would not fit easily into the cases.
