What you have in your picture looks to me like a 1st position cog and separate lockring from a modern cassette (in this case, lockring would thread on the INSIDE of the cassette), and would not be compatible with the pictured hub. If you can include a picture of the entire cassette assembled and locked into place on the hub, that would change my mind. Thanks!
