Hence a "47" marking on a 1930's pen indicate that the pen was produced in the fourth quarter of 1937, not 1947, which is a common misconception. In the second quarter of 1938 this system was however changed to save production time, and a new date code, using a system of dots, was adopted.
So in 1752 these days had to be cut out of the year to make the adjustment.
Therefore Wednesday 2 September 1752 was followed immediately by Thursday 14 September.
40 perches = 1 rood 4 roods = 1 acre Confusion arises from the fact that a perch is also a measurement of length.
A perch, pole and rod are all terms for a measurement of length of approximately 5 metres (5.5 yards).
The first date codes, found for example on the Vacumatics, consists of two digits, the first one denoting the quarter of production, the second denoting the production year.
In mid 1934 Parker began marking most pens and pencils with a date code, both the barrel and the nibs were marked, but lacking a date code doesn't necessarily mean that the pen was made pre-1935, since many imprints have been worn off with use. Compare the symbol for about a pound in weight, which is represented by ‘lb’ - it comes from the same. A shilling was represented by ‘s’, originally short for ‘solidos’, a Roman coin. A penny was represented by ‘d’, short for ‘denarius’, a Roman coin. A halfpenny was represented by ‘ob’, short for ‘obolus’, a Roman coin. A farthing was represented by ‘qua’, short for ‘quadrans’. When transcribing documents that mention amounts of money, do not expand the abbreviations such as li, ob, etc.Leave them abbreviated, and remember to transcribe li as ‘£’. Top of page Square measurements were given in acres (abbreviated to ‘a’), roods (‘r’) and perches (‘p’).For further information about measurement see Colin Chapman, ‘How heavy, how much and how long?: weights, money and other measures used by our ancestors’ (Lochin,1995).This is also known as OS (Old Style) and NS (New Style).Tags: Adult Dating, affair dating, sex dating
