In another thread here, I talked about some modern era standard gauge I recently found, including that Gold Standard Engineering GG1. Well, these two pantographs were sitting in the box the stuff came in. They are reasonably smaller than the pantographs on the GG1, but look like they are a bit too big for "O" gauge. They are all metal, unmarked and spring loaded. When folded down, the length is approx. 4.25". Does anyone know who made these?
