King's National Roll Guidelines

[MJROB]

Hi All,
Just wondering if anyone has a copy or can direct me to official guidelines surrounding eligibility for the King's National Roll employment scheme that was set up in the aftermath of the Great war to aid the employment of disabled ex-servicemen.
In particular, i'm interested in discovering whether those who were in receipt of disability pensions for mental/psychiatric disabilities were eligible for the employment programme. As the scheme applied to 'any man in possession of a disablement pension' then I'm assuming that they were indeed able to apply.

Any information would be warmly welcomed.

Regards,

MJROB
