Here's profiles of six ponies to show how distinct they are. I've stayed away from the wide ranges that are found with the diamond ponies, that's another scenario. On the left is an off-clear NWBIT; next is a light green unembossed NWBIT where I can feel the blotouts on both sides. Next is an unembossed MLOD pony in light green, then a Short Bar pony, followed by a newer diamond style and then a Hamilton base {MLOD}. The NWBIT's are unique and a lot more substantial than any of the others.
