Kye, from memory, it is getting a while back but 10 shillings became $1 one pound became $2 so the figure of 7/6 a week was seven and sixpence which equated to 75 cents. Doesn't sound like much these days but it was real money back then. 49 guineas was 49 pounds plus 49 shillings with 20 shillings to the pound the above mower actually cost 51 pounds 9 shillings so 49 guineas sounded like you were getting a better deal. Mowers back then were serious money and as a comparison I would guess that on that scale a mower should cost a couple of thousand dollars in todays money. See we are much better off these days
