Some states, like WA, have required plywood sub floors for more than a generation. Other states still do not require plywood sub floors.
If the bus saw service somewhere in the east the odds are greater that it doesn't have a plywood subfloor than having a plywood subfloor.
If the bus saw service somewhere in the west the odds are greater that it does have a plywood subfloor since it has been the basic spe'c for a long time.
Having said that, 1993 was a long time ago. At this point, unless you can get the original build sheet (which is very difficult if it is a Blue Bird) I would guess it most probably does not.
