Odd size Cellular deck

[nhstruct]

I am working on a manufacturing building, built in the 1950s'. In the area we are evaluating the Mezzanine level has what appears to be 2" non-composite cellular deck with 2" concrete (4" total thickness). I can find information on a 2" composite cellular deck, but not a non-composite. can any provide me with any information on the deck.

Thanks.

It would be conservative to ignore the deck and analyze just the concrete topping with its reinforcing.
Hopefully, it does have reinforcing.
