FIG. 2 is a top plan view thereof;
FIG. 3 is a bottom plan view thereof;
FIG. 4 is a right side elevational view thereof;
FIG. 5 is a left side elevational view thereof;
FIG. 6 is a perspective view thereof; and,
FIG. 7 is a cross-sectional view along line VII-VII in FIG. 5.
Note that a rear elevational view is omitted since it is symmetrical to a front elevational view.
