What you have is a german additive colour film of the irregular (grain) filter type. Remarkable about this film is that it was preceeding on the market (1927) the film versions of the Lumiere and Agfa additive colour materials. Technically it was closer to Agfa, though having about 2 stops more speed, but still only 3 DIN.
It was offered in a great variety of conversions.
One year later the company was bought by its german competitor. Lignose Natural Film is said to have left the the market the same year. The plant though existed another three years. The whole enterprise was seemingly the shortlived conversion of a former explosives plant.
Anyway, that's seemingly why you did not find it in the Spencer.
