I don't see any with that lens orientation their 1907 catalog. i didn't try to match it with one of their lights otherwise.

I wonder if it might be a navigation light, not a RR light.
Hardware stores often had their name or initials put on items they sold.
Wouldn't a railroad usually have "RR" or "RW" after their initials, not "Co"?
If the "K" was a little less distinct, I would suspect "Redondo & Hermosa Beach."
