Pencil Search – Success Of A Kind

Over the past few years, I would often be inspired to post this on various office supply and stationery sites:

Hi, I have a request, and I hope someone can help. In my late father’s stuff I found a canister of mechanical pencil leads, with a cork stopper. From the markings I think they are from his job in the 1960s at the UK GPO (General Post Office, which later split to make the Post Office and British Telecom). I’d love to be able to use them, but they are 1.5mm size. It’s been some years now, and I just cannot find a mechanical pencil or lead holder that will hold them. 1.3mm is too small, and they fall out of my Staedtler 2.0mm.
Can anyone tell me if there is such a thing as a 1.5mm lead holder? I’ve searched around on eBay, without much luck.
Any ideas for what I could do? Can you put the word out?

I even bought a cheaper 1.3mm holder and some thin diamond files to see if I could increase the size. That didn’t work.

It seemed nobody could help. Disappointing.

In the end, and it is a real anticlimax to be honest, I tried wrapping a piece of thin card around one of the 1.5mm leads and then trying it in the Staedtler again. It worked fine, and it even let the lead slide out when I pressed the release button.

Moral of the story? If you believe in yourself, and reach for the stars, you may only hit the moon, but at least you have a pencil.
