This is a brass track. Inside the different ties on underside of track it is stamped with the following. - Made In Western Germany - By Lehmann - LGB -NO.11800 - R=600 - GES.GESCH. D.B.G.M. - Foreign Patents Pend. and lastly a symbol that looks like a dome with a weather vane on top and a backward 9 inside. Hope this helps, I am not good at getting pictures from my phone into the computer. Thanks
