Russian cucumber 'Rytova'

[orflo]

There used to be a Russian cucumber bred for 'living room growing', it was created in 1895 by a Russian botanist Rytov. It grew well in pots in a sunny living room ,and was offered a lot in Germany in the beginning of the twentieth century. Unfortunately, this variety seems to have disappeared. Does anybody know something on this variety (Andrey or others???),
