I did not realize it at the time, but I think I know why this revolver called out to me.
No one I grew up with had a handgun, except, my Uncle. He was a Policeman in Las Vegas. His primary gun was a 357 and his BUG was a snub nose 38. He was at our house somewhere in Alabama when he asked me as a young teen if I would like to shoot his 357. We put a scrap piece of plywood at the base of a pine tree and I blew it to pieces with that 357. Somewhere in my subconscious, this 686 must have reminded me of that day.
Anyway, I picked the 686 up the Tuesday before hurricane Milton hit on Wednesday. After hurricane cleanup, I took it to the range and this is the 1st wheel load with it:
Ignore there are 8 shots, 2 of them are 300 Blackout before they told me I couldn’t shoot that on the upper deck. The 1st wheel was SA only, I have a lot of work to do to become proficient with DA!
Never one to not fully understand how something works, this is what it looked like on the inside. This photo is after I had already kind of polished up the trigger and hammer prior to disassembly. Also not fully evident, there is enough oil inside to fuel my SUV for a week!
Not fully happy with what I saw, this is what it looks like inside and outside today:
The Oh-■■■■ moment of the reassembly was when the spring that connects the trigger to the part that rotates the wheel popped out. Thank goodness I found a YouTube video where a guy showed how to install it using a $300 tool. I successfully substituted a regular old flat head screwdriver and moved forward 
I will say I am glad I do own some gunsmith flathead bits that help prevent external scratches when doing this kind of work.
Edit: It turns out this is an 8 year old revolver. I did not take photos, but the front of the wheel had a lot of lead/carbon build up on it. Again, a guy on YouTube advised not to go steel wool on it, so I used a Remington lead removal chemical to clean it up. All in all, I am very happy with it.
