Back in the 1950s, 5/- was about 25% above the hourly rate for labourers, so
today's equivalent would be the minimum wage of £4.90 per hour+25%, say
£6.12. That's a factor of about 24 to 1.

Why should the hourly rate of labourers in the 1950s have anything to do
with either the matter under discussion (currency value in the 1930s) or
the minimum wage today?

Rather than guessing, why not try one of the many useful economic
history reference machines, which is what I did:

Although only programmed up to 2002 it gives:

£4.91 in 2002 has the same "purchase power" as 5s in 1950.
£12.16 in 2002 has the same "purchase power" as 5s in 1930.
