Interesting, there ar a few more variants than I suspected.
The cassette in question is from a package I could not resist ordering one package from B&H just to see what it was.

I did not want to reveal this link at first as I did not want to get off on a lomography tangent.
For Kodak B&W I have been mostly using the Arista Premium 400 (my slightly older current stock is emulsion 1521 with bar code 010294 on the cassette and 400TX (emulsion 1721 bar-code 010294)
Curious what the Lady Grey is, Tmax400 or somethink from the back of Kodak's Warehouse. the cassettes are printed with the lomography brand, just like any other private label film would have the customer's artwork printed. The package did not have an emusion number or date on the outside.
