Does anyone have a conversion chart or somesuch gizmo that "translates" the old (presumably English) line 'grades' to current line weights (E.G. 0 - 14)? Is this even possible? I ask because I have a number of older English-made reels (Young etc.) and the company's information/booklets for these refers to line grade 2, 3, 4 etc. and there is no corresponding info.

Appreciate any info out there. Cheers
