Hi Caterpillar20
If there is no entry in the calendar and you have searched for at least 5 years after his death (actually look at the calendar pages don't rely on transcriptions), then it is almost a certainty that there is no grant or will.
If there is no grant for letters of adminstration, then the estate would have been valued below the threshold for 1961, today it is £5000.
If there was something of value and it had been on the Bona Vacantia list, then by now it would have been passed over to the Crown. Names usually stay on there no more than 30 years. The oldest entries on the current list goes back to 1974, 1977 and 1978, the bulk of the rest start in the 1980's.

If there really was nothing of value and he was in rented accomodation, then his landlord may just have disposed of the furniture and clothing.
However, if some sort of contact had been restablished with a family member, they would most probably have done the same thing.
I know this sounds harsh but this even happens today. My aunt, acting as executor for her late sister in law, earlier this year had no option but to dispose of everything, no charities wanted the furniture or clothing as it was too old or not in good enough order. There was little money as she had been surviving on a state pension. She has sold the house but the value was greatly lowered as it was in need of complete renovation having not been decorated in years, rewiring needed doing, double glazing to replace all the windows and central heating installed.
