Apparently still around, just not making mechanical pencils:

"Trevor's son, Geoff remembers starting to help his dad make the first gas taps in about 1961. During this period the company also manufactured the well-known Keefer propelling pencils."
He looks like he's had some keef, alright.
I found another ads about this Keefer Goldtone Pencils. https://nla.gov.au/nla.obj-550354064/view?sectionId=nla.obj-552663332&partId=nla.obj-550370917#page/n25/mode/1up
I can give you a fancy pencil if you go out with me.
I want a girl give me a pencil on date.
