I put together this lovely 2-way blinker from spare signal sections. The hardware is what makes this piece cool to me. I like the perpendicular line theme running through the solid spacer, the slip-fitter, and the weather cap on the hollow bracket. I got the set of Marbelite aluminum brackets from Scott Signal, a former supplier of vintage signals and parts. The 54″ post and the Marbelite slip-fitter were supplied by Twin Green, which is still in business.
The cutaway visors are actually perfect Marb-style reproductions made several years ago by Steve Tutty in Colorado.
