I remember my DM baking bread too and it was exactly as you describe! She used to put the dough in a polythene bag to rise on top of the electric oven.
I was born a year after they introduced decimalisation. I remember mum saying "old money " all the time!
In the 60s/70s, DF was a delivery driver for Corona pops! Then a milkman in the 70s/80s.
We lived in a rural area and I remember a van coming round selling groceries. I used to save my pocket money to buy a whole pack of Viscount choc mint biscuits!
I miss the "good old days"!
