I've a 2954 prewar scale box car with a broken roof walk that I need to open up to replace the part. There are four pins at each corner that hold it together, but I cannot tell whether they are simply a friction fit pin or a screw. They are not loose when I try rotating them and do not want to break the casting trying. So I am trying to find out from you all whether I need to wiggle them loose or try to rotate them out, i.e. are they just a pin or a screw.
There was an earlier thread on this topic, but it did not say how the pins were removed.
Appreciate your help.
