John,
Thanks for the input. After going through some of my books and taking note on the switch stands I would have to agree with you. I noticed about 95% of the high stands have the circular targets. The few diamond targets that I noticed were at the north end of the Chama yard, as can be seen in a photo in Dorman’s book.
I guess this gives me the liberty to model high or low stands where I choose and no one can say I’m wrong, or I can develop some logical ‘standards’ of my own. Now all I need are some switch lanterns to go on top of the stands!
