Dig a little bit of digging down in the attic and found I had the
W.W.II version for the M1 rifle which has two halves and a similar
flat webbing belt between for adjustment. A bit more digging found
a pic which shows that indeed #563 is only one half.
I've combined with #563 so a comparison can be made:

BTW LCC & Co. stands for L C Chase & Co.

Thanks for nailing this one for us.
