Information wanted on old unusual record.

[Arkwright 10]

I recently purchased an old Kodisk record off BidorBuy, and would like to know the history of this record, and how to properly clean it before playing as it is quite dirty. If anybody can help, I would realy appreciate it. Here is a picture.
