Does anyone know the size limit (largest number of teeth) on the freewheel that can be safely handled by a Nuovo Record rear deraileur?

To simplify the question, can it handle a 28 T cog on a freewheel that is 13T or 14T up to 28T? Would that 28T cog hurt the deraileur? Would I be better off (from a rear deraileur performance perspective) to stick with a 13-24T rear?

I'm not yet sure what I will have for chainrings but I suspect it will only be a 3T differential from large to small. If I went (worst case) 13-28 in the rear, is there a limit on front chainring differential due to rear deraileur capacity?

I used to know all this stuff (40 years ago). It just isn't clear any longer and I don't want to hurt (break) anything.
