tapered or butted spokes

[ajleone]

I am looking for a set of spokes are for a narrowcase Ducati 4-speed Diana. The bike has 18 inch M. Baruzzo rims, which are very narrow and the double-butt spokes. The part number in the parts book I have is 055.77.113 and lists the description "Reinforced spoke 3.5 x 3.0 x 3.5 x 153mm". These are for the front. As it turns out I acquired 2 sets for the rear (157mm).

I have and extra 36 inner 157mm double spokes for trade if that helps.
Thanks,
Tony
