Pre-unit Triple Tree Identification

Two types of pre-unit triple tree tops. The one on the top has a flatter front shape and the nacelle mounting bosses are smaller. Anyone know the difference? My guess is that the top one is earlier, but it has no part number. I have a couple like it and they both have a triangle type signia cast into the top. If you can identify years used on these please comment or email.
