Cam cover breather tube

There appears to be two breather tubes for the cam cover. The second shorter one (24912-52A) doesn't appear in the parts books until 15 Feb 1957. Does anyone have an idea when the changeover occurred? I couldn't find anything on this in a search on forums or in the technical section. I apologize if it has been touched on previously. Mark

Mark, My OP '56 KHK has the double bend breather tube on it and it's Vin # 2268. A friend has a '57 XL that has the single bend shorter breather tube on it. His Vin # is 3144. It would appear then that the shorter tube first appeared on the '57 Sportsters.
