Parker Pen cap part spares repairs

I am having a clear out of all my Parker bits.

Unsure which model this is for, maybe a 45 Arrow or Slimfold. It is threaded inside the cap. Looks new old stock or very good used condition.

Black plastic with gold trim

Please ensure this is the correct part for you before bidding. Happy to answer any questions.
