Here's some photos. Can't seem to figure out how to post them so they'll show up in the body of the post...

Sorry, I just figured out how to post a few pictures. Maybe now this will make more sense...

Help! I'm trying to restore my old 97 coal elevator solenoid (the one that releases the coal from the building with a spring-controlled trapdoor). However, I'm giving up hope that I can remove it without destroying it. The portion where the spring meets the solenoid has me stumped- can this somehow be taken apart?
