Wray Lens Question?

[JDS]

Hello all. I am new here and need an ID. Could you please tell me if this lens is for enlargement purposes or ??? It has a detachable mounting ring. I wish to sell it on eBay but want to at least know what I am listing. Any and all info is appreciated. Thanks.

The VM says it is a dagor type copying lens that can be used as a taking lens, also that it is best focused at f/8, shot at f/11 or smaller and that it covers 8x10.
