1500 Lifetime pen and pencil set. I’m reasonably sure that it comes from 1963, the first year for this style of marking. When I got this pen, it still had a sticker on the barrel which said “CARTRIDGE”, which gives a sense that a self-filling option might have been expected by the buyer.

I’m including several views of the case, as it’s unusually splendid.
The instruments themselves rest upon a bit of a pedestal
Under the pedestal, a supply of ink… but no leads for the pencil.
