That was a lot of work Bryan.

I was just curious about the 60s to the beginning or mid 80s. If I wanted to know when the Crusader first entered the scene or the Phoenix series, I could look on the list. Or if a plane had a certain design change, did others have that too that were designed before it?

I'm not in a bet with anyone that I'm disputing a date on, just curious if such a list exists. Like your list, it would be a lot of work.
