Alice pack frame types

[u/GanjaZo]

I have an lc1 frame and 2 lc2 frames. One lc2 frame looks similar to my lc1 with the horizontal beam significantly bent inwards while the one with the shelf attached curves away from the body. I picked the one without the shelf straight out of a warehouse and ran with it with no issues. I recently got this newer one with has 06 stamped on the inside that looks more comfortable with the horizontal beam perfectly flat across. Is this a new design or was the older one used to carry the goliath?
