Where is the missing Head Boys Board ?

Chaps and Lassies,
Many of you may remember the Head Boy boards hanging in the dining room at the school.  At the sale of the school contents I was lucky enough to acquire the one with my name on it covering the period 1957-77, and I am also the custodian of the last board (1978-91) which was acquired by the Hallmark family. There are two other older boards (1903-20 and 1921-38) hanging in Clive’s Fruit Farm cafe, where we hold the Association committee meetings.That makes just one board (1939-57) missing. At the next reunion, which will hopefully take place in late 2022 (subject to progress in further minimisation of the risks from Covid) it would be great if we could show all five boards at the event.So, does anyone know the whereabouts of the missing Head Boys Board ?
I would love to see a photo of said item and also hear from the owner, particularly if he/she is a former pupil.
