On the left is the same first gear assembly with the snap ring removed. Now you can see the synchro ring, the sectors and the semi-circular strap (note: only one strap).
On the right is a 2nd through 5th style dog gear with the synchro ring, sectors and and a pair of semi-circular straps. Note that the sector at 12 o'clock is different on the first gear, which has a tooth pointing downwards. Notice, too, that the dog gear has a gap at 12 o'clock for the sector gear tooth in addition to the gap at 6 o'clock for the smaller sector. The 2nd through 5th style dog gear only has one gap at 6 o'clock for the small sector.
