I found this quote in Hansards from a Commons Sitting on the Army & Air Force (annual) Bill dated 21st April 1926
Mr. Johnston states:
"....... As the law stands to-day, I understand, if a boy joins the Army by giving a fictitious age, his parents may secure Ins release at once if his age be under 17. But the boys between 17 and 18 can only secure a free discharge if their pa-cents can prove real necessitous home circumstances."
