Perhaps some of my wiser and more learned colleagues can help with this? Why, does it seem nearly impossible (for me at least) to find these semaphores? They are listed in Lionel catalogs from 1920-1927 and maybe after but for some reason are a very elusive critter to locate. I've seen examples at the TCA museum and photos on line (limited) but am really wondering why they seem to be non-existent? They can't be that rare?
Thanks,
John
