On close comparison of the two photos however, there is nothing to suggest the dropouts in the two photos are actually different; only that one set has been brazed into a frame, with brazed eyelets added. So now I'm accepting
JohnDThompson's assertion that they are in fact stamped, abeit with significant post stamping prep to make them look "nice". Either that, or a quasi-forging process, where the stamping die is not merely a cookie cutter, but has a female contour that creates the rounded edges that are so evident in the photos.
Well I suppose that's possible and I sure don't know everything about stamping dies although I've worked in a shop that made them. (But not as a diemaker). I do know that brass brazing eyelets onto sand cast grey iron is a dubious practice (grey iron brazing or nickel rod welding is the way to go for sand castings) so I guess I'll have to take his word for it. He should know after all.
