Hi Emma,
You may ask for information at https://memorial-archives.international/en/entities/show/546f87be759c02ca678ccbd4
As you may see, they have more on Malvin Weiss born Jan. 25, 1913 in Onod. Malvin's prisoner number is indeed 62225 transferred from Ravensbruck to Venusberg.
I think that the best way is to ask for  information at https://arolsen-archives.org/en/search-explore/inquiries/information-for-relatives// From my knowledge, they always reply.
