Felsted school CCF cloth titles

[Expat Yeoman]

There are three (at least!) CCF shoulder titles for Felsted, as per the attached image.

Presumably the green and yellow is representing the school colours and purple and yellow the Essex Regiment. Whether items one and three are colour shades or distinct patterns I know not.

Can anyone help to put dates of use to them and / or put them in order of use? I have contacted the school but nothing heard so far.

Many thanks in advance

Michael
