Thordarson Transformer info

I found a couple of Thordarson Transformers in a scrap pile. Tested continuity and seems good, couldn't find any info on the catalogue online. The models are T 40378 , T8424 ,6792 ,T69S75 . I think the later are output transformers . Any info would be greatly appreciated.
