MSD yay or nay

I have used a msd coil, distributor, and ignition (6AL) in a couple cars, no complaints. I WONT use the new digital stuff. I prefer 20 or 30 year old stuff.
I am also using the old pre-msd Mallory box that weighs 20lbs. Flawless for thirty years.
I also have a msd box, that still works, that is so old it only says msd on it, no model number. They only had one model then.....
Is your old msd a gold colored one?
The first ones I saw were a lite faded gold color with what looked like a hand written ser number. If I remember correctly it had a pigtail with about 10 wires you could wire into your car.
This was in 1974 so the Chrysler electronic ignition was barely 2 years old.
