Here's a beautiful Wearever pen/pencil combo from the US in marbled celluloid.

I've replaced the J-bar and given it a new ink sac, as well as cleaning and resetting the nib, so it is in working order. The nib is in good shape so it writes well. There's a little bit of lead in the pencil end too, but I'm not sure how much.

There's a bit of plate wear on the pencil end and on the cap rings, but it's a lovely looking and interesting pen for your collection or to use at work.
