Parker also released the same salvaged silver made into the slim button actuated Classic ballpoint pens. It had an equivalent wooden box as the fountain pen package, though slightly smaller in size. It even had a doubloon (cob coin) replica also made out of some alloy that may be pewter.
A close-up of the cap band shows the familiar inscription.
If you have any information from Parker about the number of these BP packages made, please let me know via email. Unlike the FP, this is an unknown quantity to me.
