Quoted from High_End_Pins:Most for MM 1 needs a lot of help.
Really we just need a new moat,sockets,bulbs,switch and wiring
Okay an all new moat. [quoted image]
So these moats can be hit and miss to find. Often out of stock I found this one at Marco when others were out of stock so there may be a better or worse one available today but when I was gathering parts this is what I could find. A little opaque or frosted looking underneath but shiny inside.

Since I need to build it up from scratch I can choose the socket styles I think would work best.
Original is the 89 round style
But there is no reason I cannot use the 904 wedge style

I think with the use of LEDs these days and how far that has come that I like the cleaner look and ease of bulb changes with the wedge style so I will go that route for MM 1. It needs everything anyway let’s do the best we can to improve it. [quoted image]
Sockets in place.

I think the wedge sockets have less resistance to vibration than the bayonet Style.
I think that's why they are used in some places and not others.
Just a guess.
