thanks to all who answered my previous plea for help I found them to obscue fo my blinkered vision just one more to go before the sheet gets recycled. M.O.T.F.S. The above suggests a festive season theme thanks again to all participants.
Purely as a tentative suggestion --- 28th December is Holy Innocents Day which commemorates The Massacre of the First Sons by Herod.
No matter what -- OT probably equals Of The.
Sorry I can't be of more help.
