Here's a beautiful Olive Green glass spool from France with an unlisted embossing: F.L (front) No 23 (Reverse). This rare find measures 1 3/8 inches x 1 3/8 inches tall so its a candidate for a new cd number too (most likely a CD 1081 variant). And the news just gets better- this insulator is easily VNM+ shape with only 2 very teeny base rim flakes and the "No" is faintly embossed. F.L is abbreviation for Folembray.

The first email can get this rare unlisted gem for only $75 plus postage. Thanks Bud
