When I first got this I wasn't sure who made it but after submitting photos to a couple of Yahoo discussion groups I belonged to the consensus was that this was made by Schumann of Germany, probably in the '50s. My example is missing the linkage to the semaphore blade, and the pole has a couple of tabs broke off at the base making it lean but I think these will be easy fixes - once I get around to it that is :-). Buying less than pristine items can be a good way to acquire nifty items on a budget and I'm am certainly not above saving a buck on a purchase! Eventually I'd like to add this to a planned 2-rail clockwork layout. Enjoy!
