Yes, you're spot on with Bell Fruit in Nottingham.
Hayes "British Machine Tokens" lists 78 different tokens from this issuer, and that is just in the original catalogue. There are more in the supplements and further that are unlisted, including overstrikes and other oddities. Yours is 49.76 in the catalogue.
They're also interesting in that they span the period before, during and after decimalisation in the UK (1971), so you get otherwise similar tokens with just £sd values, with both £sd and decimal, and just decimal. Yours exists in a variant where it says 5/- instead of 25p (49.41).
Malcolm's your man for more info on these, I think!
