Any idea about this lens? Are they similar to Dagor type lenses?

The Vade Mecum says it’s covered by the patent on lens design Voi013, which looks just like Figure 6.11 in Kingslake—a symmetrical 3+3 like a Dagor, but with a different arrangement of elements.

Seems they were the competitors of Dagors then.

Yes, they are but not the same, I have seen Dagors of all sizes, Collinears are much rare in big sizes and you could see Dagors in many cameras but Collinear normally in Voigtlander ones.
