OTC & CCF cap badges 1979?

[sailorbear]

Hi all, a couple of questions I hope someone may be able to answer?

Cranleigh School, Portsmouth Grammar School and Christ's Hospital School Horsham, did they all have CCF units in 1979, with their own cap badges?

Oxford University, London city University and Cambridge University all have OTC units, I assume they all had OTC units in 1979? where the cap badges the same as the current ones worn?

And lastly does anyone have a definitive answer to how many CCF and OTC units there were in 1979 (if any such information is actually available?)

Many thanks

Tony
