The 121mm Edco bottom bracket sold by Velo Orange is too long for that crank.
I'd try to keep the spindle that came with the crank, since it's the right length and offset. I'm not sure that's a thick-walled cupset you have, but it's hard to tell in the picture. If it turns out that you need thick walls, look for a set of rifled 35 X 1 Campagnolo Nuovo Record cups. They have thick walls. I see them all the time on eBay and have bought some myself.
