The double sided walk in galley I think is the aft one. The recovered piece I think is from the forward one (the 200 numbers), and if it helps it does not appear to have the counter, that might tell someone more familiar if it was facing forward or aft.
Shame you can't see the numbers in this pic, but it has the counter, so if my suspicion is correct the recovered piece might sit directly across from one like this.

Hopefully someone with more first hand knowledge can sort this out.
