If they are long cylindrical shape, they could be old window sash weights...I've still got them if anyone in south DFW wants them. I have no use for them and have no idea what the hell they're for.
My problem is, I'm in north Dallas, up by McKinney (Allen) Do you ever get up into the Plano area? I don't mind driving a little bit, but I-20 and 360 is about a 40 minute drive one way...
