I think you folks would know better. Looks to me like 3/4" or maybe 1" stock that has a saw slit down the middle. Then forged to open up the "V". It doesn't look like the "V" itself was forged 180* back on itself.
The inside of the "V" doesn't really look cleaned up too much. Maybe surface ground to true up the top and bottom. There does seem like some nasty inclusion down where it's being held. I'd bet as they were slabbing off springs, they might not want to use that area. Surprised it doesn't make the whole piece suspect, because not much is invested up to that point.
I think it's so bulky just to make sure the pattern of a spring fits in there without too much worry. Maybe, but that rough stock doesn't look like much advantage would be gained up to that point with EDM.
