Subject: [CR]Bluemels timeline question

I wonder if anyone can point me to resource that will give me the Bluemels models that were available in the 1955-1975 time frame and when those models first appeared withing that time frame. Specifically, I'm interested in the All Rounder, Sprint Veloco and TdF alloy (full version). TIA.
