Verne’s Hybrid OP

This was once a popular plant but has become rare due its chronic infection with various issues including fungus and TMV. So much that it gained the nickname “Vernes mosaic”.

I am preparing to remove several large plants at the cactus affinity nursery and about 50’ of cuttings (8 x 6’ cuttings) are available for pickup in Chico, California.   

Verne would sometimes switch up the order and called this one both SP x peru and peru x SP. He wrote on his websites that Koehres once sold these hybrid seeds, but afaik he never clearly stated that this was source of his plant. Did he grow it from one of those Koehres seeds?
