railroad-trolley parts from 1940s

Description

railroad -trolley parts from 1940s my 92 old neighbor found this railroad parts on his property the previous owner of the property was a railroad engineer there from what I gather is they come from the tracks that once went up west chester pike in Pennsylvania  out front 30ft away is house so I don't know a lot more than that they my be from different track and time butt it makes sense  they are in good condition for the age solid steel just surface rusting
they sell as is and no guarantee as origins as I'm not a train expert  there is a maker mark if you know your stuff
