What are the major differences between a Browning BT-99 and a BT-100 ?

I have a BT-99 but have never seen a BT-100.

I know what the BT-100 does have, since I have one: Ported barrel, drop out trigger group where you can adj trigger pull and if the shells eject or raises up, adj. comb, high rib, and higher grade wood.

I believe you can get the 99 with everything above with the exception of high rib and drop out trigger.

The drop out trigger really helps when it come to cleaning the gun.
