My two have very different trigger guards. Earliest one seems longer and the spur doesn't seem to curve down as far. Later one was converted to easy open, but has greater curve down, is milled out where the trigger guard bow and backside come together and also has a trigger stop screw.
Just fyi, Both have the screwdriver rim to rimless hammer selector, but the easy open has a 'safety' slider in the hammer to prevent the hammer from hitting the firing pin.
And, how about a link to somewhere that the differences/history might be found if it exists.
Thanks.
