Bellevue Washers Source for Sherwood Magnum?

[JamesBon92007]

Okay, I just spent far too much time trying to list all the known Sherwood regulators over time. (but not octos, I'll come back to that another day) And I may as well post it here.

I have tried to list these in an approximate chronological order, but don't take my sorting as bible. My first priority was to group items together that use the exact same 1st stage. Sometimes I just assumed what was older based on the look of the service manual. It does NOT seem like model numbers are a definitive means to sort old to new, just an approximation. Where I could find actual model numbers for separate 1st and 2nd stages I provided them, otherwise I left them blank.
