(a)he is entitled to an increase under section 104 above of a disablement pension and the amount of the increase is not less than the amount which at that time is specified in Schedule 4, Part V, paragraph 2(a); or
(b)he would have been so entitled but for having received medical or other treatment as an in-patient in a hospital or similar institution,
