Binding post sizes

In the late prewar and post war eras, there were three binding post nuts. They are 88-2, 4-36 threads; 1033-47, 6-32 threads; and T-160, 8-32 threads. Not long into the MPC era, a few metric binding posts started to show up.  There are many different length and styles of binding posts and it is a more difficult item to nail down.  Late in the post war era Lionel switched from the machined plated brass binding post nut to a sintered aluminum nut. They are part #7-something and come in the three different threads same as the earlier nuts. These are best replaced by the earlier plated brass nuts.

Thanks. I was able to order a batch of the e different nuts and a pack of the 4-36 binding posts from Trainz. A good first step.
