I was recently reviewing some older emails and came across a note from Tom Wadnola regarding the S10 Vigil flap from Half Moon Lodge #28. It appears that at one point the flap was reordered, and the differences seem to be enough to warrant an a and b variety.
The newer variety is wider from side to side and a bit narrower from top to bottom. The lettereing in the new er one is dark green and the you can see white under the mylar border.

The Blue Book stats should be:
S10a SMY R WHT GRN GRN FDL;PB; VIG; 50 x 114mm
S10b SMY R WHT DGR DGR FDL;PB; VIG; 48 x 117mm
