Help needed with cross classic century

[Ddd213]

Hi all! I've just joined the forum, as I'm looking for help with a vintage Cross ballpoint (classic century?) such a Beautiful pen and I fear I've ruined it... Was trying to get the refill out (I know I know, read the instructions) and somehow unscrewed the refill *holder* instead of just the refill. The spring and 2 little washers came out as well. For the life of me, it won't all go back in! It's like the refill holder is too big. . Is this how it stays in..? Friction? And once it is out, can it ever be put back? I am beyond annoyed with myself.
