Almost certainly. One of my rugby and maths teachers (!) had a similar one for that reason. Now the 2 1 7 and 6 for the peppermints is an odd thing. I presume it is the price but my first effort is: 2 for 1, 7/6 ie 2 for the price of one for 7 shillings and 6 pence but that was quite a lot of money.
