Here's the top view. There are two small protrusions on the top edge. It doesn't match any listed spool in either the McD books or the GIFONA. Does anyone have any idea what CD it might be, or any other info on it. The person I got it from says it is of North American origin. I suspect it might be an LRI. Any LRI experts care to jump in? See other pics posted for other views. Size is approx. 1-3/8" diameter by 1-1/2" tall. I forgot about this pic. The LRI gurus chimed in, and this is definitely an LRI.
