I inherited these pieces from my father. I think they were my grandfather's (born 1899). The three look to me to be by the same manufacturer- the litho pattern repeats. The telegraph pole (I have 4) someone else here identified as Marklin from around 1905, so maybe more of this is Marklin? The one streetlamp looks like it had a wick and burned oil- the top unscrews. I'm very tempted to fire it up.
Someone has soldered the semaphore and it has broken loose. I don't know how hard this would be to resolder but if anyone has experience with this, let me know. I imagine this mechanical semaphore saw a lot of action.
I do touch up my later Lionel prewar that is going on the layout with oil paints ( I am an artist and can match the colors pretty exactly) These are old enough that I think maybe I should leave well enough alone.
As always, I am in awe of the considerable knowledge my fellow tinplaters have. I haven't seen @Arne around much, but maybe he'll see this.
