The comprehensive guide I mentioned is more updated than others and is easy to follow. If you look at the L series some of the older time lines are not as complete as @mata_66 minus pictures. I combine it with some of the other timelines you have mentioned and his comes way out front because he was able to use some of all timelines and he can update anytime he wishes and it's a complicated puzzle to figure out for anyone who enjoys this hobby!That information is the same old outdated stuff.
This has the most current revisions and I don't claim it to be fully correct. I need to still put up the I and J adverts which I have but just haven't gotten around to doing yet. For example that 1976 championship razor you have I need to find some documentation on since I only thought it was produced in 1972 and not also 1976. The 76 one most likely was a Canadian only razor.
