Gutterman 110yards empty spool: 4g
Old plastic Coats 100 yards empty spool: 5g
Old Wood 125 yards empty spool: 6g
Old wood larger empty spool (more like a 500odd yards spool) 15g
Old wood large "Other" empty spool: 11g
I don't currently have an empty large gutterman spool, sorry.
All weights are very approximate, it's a little digital kitchen scale.
I would love to be able to rewind the old spools. I like the feel of them better too.
