As little as that? Hmm..... you could support a family on
£300 a year, back then, and now you would want, what, a
minimum of £20,000. Okay some things (notably communications)
are infinitely cheaper now than they were then, but if you
express 5 shillings as a fraction of the annual salary,
it would be more like £2,400 of today's money.

Uh? 5/- is 1/1200 of £300. So today's equivalent would be 1/1200
of £20K = £16.67 surely?

Probably, probably..... never very good at maths, I wasn't.
