Cross 1/20 10kt Gold Filled Pen with Case

Got this vintage Cross pen here. It's 1/20 10k gold filled and comes with the original case, manual, and even the outer case cover. Just a heads up, it's currently not working. The twist mechanism seems stuck or something because I can't get the pen tip to come out. Selling it as-is for parts or if someone knows how to fix these things. Still looks pretty nice though.
