My LFM-2 doesn't have a plexiglass top with film cover. It has a fiberboard top, flush with the black case body. Thinking the biberboard would come off if only I tried hard enough, I gave it two tries, losing part of a fingernail and the tip of my pen knife in the process. I'll try to upload a picture to show you (never tried this before).
