Comparing Billingham Combination M (for Leica) with L2

There are many information over the internet which most of its telling that both Combination M bag made by Billingham and Billingham L2 are identical to each other, one place show the table of dimension which exactly same size either external and internal.
This made me doing a bit of trial start with the Combination M and later with my friend in Singapore can send me the L2 one to compared with result as following, and I can tell you that both are not identical and both are differences bag with differences set of camera and lens can fitted.

Top view: show how setting

Front view: left is Combination and right is L2, L2 a bit wider and taller

Side view: L2 is deeper

confirm the base that L2 is bigger

setting inside: can fit 1 M8 body with 1 lens on, one side did separated to be able to put in 2 lens side by side
and the other side just simple for the 4th lens, all together 1 camera and 4 lens can carry with easy handling

On the Combination: 1 M8 with one lens in the middle also, but both side and fit one lens by one slot,  all together 1 camera and 3 lens and carry with easy handling.

one reason also because of the top entrance of the main room is too narrow? may be.
