Hi everyone! I’m new to this forum and I’m trying to get some advice on how to remove a collector and pick up assembly on a prewar 752W city of Portland locomotive. I recently purchased this locomotive and when I received it the main power pick up wire was not connected. I’ve rebuilt a few prewar locomotives but haven’t encountered this problem. Is there possibly another way to do it?  I usually use YouTube and the olsen’s Library to figure stuff out but my friend suggested that asking around here might be a better solution. Thanks in advance for your help!
