Add a memory or information about this object
- I still have one of these machines. It brings back fond memories of my father George Mothers, who in the late '60s and early '70s was a mobile greengrocer. I used to travel with him on his rounds to Peterborough and the RAF camps at North Luffenham and South Witham. It too was converted to decimal in 1971 by Dennis, the service engineer of J H Todd & Sons, Lincoln from where it was purchased.

- This pre-decimal machine has had the conversion from sterling.
Note the blanked out 10d and 11d keyholes.
Gosh, I did dozens of these in the 70,s prior to D day.

- I am 67 years old and still have this wonderful calculator to do all my books. Trying to get replacement ribbons is a nightmare, but I just cannot bring myself to part with it. The grandchildren are always wanting to have a go. Keeps them occupied for ages!!

- My grandfather was a shop keeper and he had one of these machines.
As a boy I used to have a go on it.
I marvelled at how clever it was. I guess I must have been around 7 years old.
