used LA-LF, a most attractive strip of six apparently showing postmaster's trial separation with razor cuts between LB/LC and LD/LE (almost severing but with portions of margin intact at top and bottom) and showing evidence of similar cuts along the base of the strip, good to large margins (LA close or just touched at left), very neatly cancelled in black; LB with vertical crease with another running through the margin between LE and LF, a rare and most striking item.
