Kev,
Sorry for the delayed response but I’ve had a rather busy couple of days.
The idea is a good one but you are getting involved in quite a busy area regarding oral histories and the like. I’m involved with several such projects both personally and professionally and there are a lot of organisations doing similar things, often with a lot more funding support behind them both from HLF and other funding bodies.
This might be making people reluctant to ‘join in’!
As a suggestion it might be worthwhile following up a contact via this weblink
http://www.modoracle.com/news/Armed-Forces-Day-Events_27081.html as they have grants available that might cover this type of project. That said it is quite a detailed application process.
Good luck!!
