I'm trying to find more information about this pencil, a Vacumatic pencil Non-stop/Repeater.

So far I thought that Vacumatic pencils are twisted operated ones, but after reading in a catalog, it looks like there are some of them by cap pressing operated.
Is anybody out there who can shed some light, pictures, lead size, opinions about this model? I really want one now...



This is where I found about the pencil:

And here, down to page 9:

There are 2 of them on Ebay now, but one has astronomical price, plus postage and import taxes makes it ridiculous expensive for a pencil. The other one has an ugly scratch/signature...
