I am in need of 4 Parker 51 caps...
2 Aerometric caps and 2 Vacumatic caps... one of the vac caps does not need to be a blue diamond as the pen is dated 1948.
These are for user grade pens so the caps do not need to be fancy... good basic, nice looking Lusterloys will do
Obviously, I am not looking to spend a fortune and I might have something you are willing to trade for...
