Kevin, it's Pinus mugo 'Nymphenburg' instead of 'Nypenburg'...
Google gives the following info:

Here is a link that might be useful: Pinus mugo 'Nymphenburg'

The picture on hulsdonk's website of P. n. 'Nymphenburg' appears to have a lot of needles that are long. Larry Stanley's description appears to be correct....very little needles and looks like a buds. That what I heard about the plant. Hulsdonk's picture doesn't look like anything special to me. I could be mistaken though.

This is the history of this real miniature ball shape form:
It was found by the Horstmann Nursery as a witches' broom in a Pinus mugo var. pumilio at the Botanical Garden in Nymphenburg, Germany.
It's one of the slowest growing brooms of this species, the yearly growing rate will be about 1 cm.
Both, the needles and the branches are heavy twisted.
