Hi Loco: Thanks, that is correct, Tortoise Switch Machines.
That Sir, is outstanding. These are elec. thrown correct?
Hi all: If anyone is interested, I've uploaded a "How I built and installed operating switch stands" in my yard, on my PhotoBucket site. These are Atlas Custom Line #6 with Tortoise switch machines, and Details West SS-914 switch stands. I'd like to thank Wolfgang Duddler for his excellent tutorial on his web site and Ray, (Howmus) for his inspiration to get started on them. Here's a few before and after shots.
