Once the speed ring is off take another picture of the shutter and post it here.
Okay, removed Faceplate, Speed Ring and Speed Cam as per your helpful instructions and without issue... they were all stuck together by a fairly decent amount of residual lubricant and grime. Inside seemed pretty dirty too but not as much oil.
Figure 1
Upon initial (and completely untrained) inspection, with my fingers softly applying pressure to the Cocking Lever and Ring and pushing/pulling the Preview Lever in and out, I couldn't ascertain any immediate cause of issue but it was clear that the end of the lever was suppose to be pulling or pushing another component in order to open and close the Shutter Blades and in it's current state, it wasn't connected to anything.

I know I should've waited for further instruction, but curiosity got the best of me and I carefully unhooked the Cocking Spring from it's post and removed the Cocking Lever/Ring so I could have a better vantage... Behind the downward bent crook end of the Preview Lever Arm (figure 3) where the red arrow is pointing, there is a knob of sorts that controls the shutter blades (it's not visible in these pictures and I apologize for that, but I assure you, it's there!). There are (at least) two other components in that immediate area that all feel like they should connect to each other in some form or another. After some careful observation and experimenting with the tweezers to see how the parts moved and reacted, (during this bout of fiddling and inspection the shutter blades snapped closed!), I surmised what I thought to be the proper alignment of each piece in relation to each other.
The trick was that the shutter had to be cocked for me to be able to line everything up and properly lay in the end of the Preview Lever. I'm sure there is an easier and more proper way approach this, but what I ended up doing was carefully placing the Cocking Lever/Ring slightly back into place paying attention to it's fit in relation to the other components, while doing this I was also presetting the Preview Lever making sure everything was lined up and ready to go. I then cocked the shutter and finagled the Preview Lever Arm into place, I'll be honest, it took multiple attempts and a fair amount of trial and error. Taking the Cocking Lever/Ring off and starting again several times.

After realigning the Cocking Pinion teeth to coincide properly with the teeth on the Cocking Lever/Ring, I cocked and fired the shutter multiple times and observed the movements (and sounds), everything seemed to be in order. I tested the Preview Lever by carefully pulling it out and pushing it back in, the blades were opening and closing properly! Time to button her up! I swabbed and cleaned the excess oil and dirt from the Speed Cam, Speed Ring and Faceplate before carefully setting them back into place, rotating the Speed Cam and Speed Ring in unison to make sure all the contacts were aligned in their channels. Faceplate, Retaining Ring (noting the number of turns) and Retaining Screw back in place, I took a deep breath and held it as I cocked the shutter, fired it... SUCCESS! I cocked it again to now check the Preview Lever action... Success again! After several more cockings and firings at different speeds to be sure everything was in order I let out a long-winded sigh of relief.

I'd like to eventually open this bad girl up again for some cleaning and very light lubricating... any suggestions or advice based on the images above? I was thinking of pulling the Speeds Escapement out and giving it a bath in alcohol, spraying non-residue electrical contact cleaner in and over the rest of the shutter mechanism(s) then applying a few dots of oil to the gear pins in the Speeds Escapement before placing it back in the assembly...
Thank you again for your words of advice, guidance and encouragement! Much appreciated!
