I am 99% sure.. the way I remember to identify them is that 93 has cable routing on the drive side and straight stays. 95 has snake stays and brake cable routing on the nondrive side. I forget how 94s are set up, but they have either nondrive side cable routing OR snake stays, not both.
Here is a pic of the 93 catalog, you can see the cable routing is different. I think the 95 frame is better.. the cable routing on the driveside for the rear brake makes for a tight bend in the cables that doesn't look as clean.
