Thanks Jim. Yeah, the old spokes are 307's it looks like. Something else just occurred to me. Old Nisi rims had no eyelets and washers. New rims have eyelets. This could be tricky. The spoke calculator I used called for 306.2 mm spokes for Sun M13 II rims, cross 4, so it may work out. But I'm not too experienced of a wheel builder.
