On offer is a Classic from the fifties (approx 1954) a "Times Savings Clock"
That was used by people on a tight budget and gave them an easy way to pay for things like Insurance policies etc.
The Clock only worked if a Two-Shilling Piece (florin) was inserted and this ran the clock for 1 week then another coin had to be inserted.
Periodically someone came to empty the Clock and this paid for whatever service was required ie Insurance premiums etc. (Requires new spring)
Grab a Rare Piece of Nostalgia £15 (postage if required £5 extra)
