Here's a pic of a small spool that I recently received. 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 top and bottom views. Size is approx. 1-3/8" diameter by 1-1/2" tall. This is definitely an LRI, of the spool style.
