I can't really say about other variation. The Roll Engraved rifles were originally labeled as Salesman's Samples. As it became clear that there were too many in circulation to be salesmen's samples I started collecting data from Forum members and at gun shows.
I think I have a pretty good idea of when the Roll Engraved (this would include the ones sold by Spiegel...not sure they were all sold by Spiegel), 99-H's, 1960-E, Spain rifles and RT's were produced and how the calibers fall out. Drew has a pretty good list of R/RS's, also. But it is hard to tell what part of the total the samplings cover.
Other variations have just been added when available (and I don't save data on every 300 EG I run across
) so can't always tell commonality by units collected.
... no way. I hate public speaking and memory is not good enough to remember all those bull crap lines they use.
