Kirchainer mating nuc dimensions?

[buckbee]

Ruttner mentions the Kirchainer polystyrene mini mating nuc, which apparently has top bars and sloping sides. From his illustrations, it appears to be about 8-9 inches long by maybe six wide, but their is nothing in the picture to get a sense of scale from and this could be way out. Google - for once - doesn't help, so does anyone know the length, width, depth and frame spacing in these little nucs?

Thanks Michael - no wonder I couldn't find it, Ruttner's translator spelled it differently...

Have you ever used them? Looks like a good solution for the TBH man, especially. Oh, and the TBH woman, of course...
