Bristol IMPs: Linear Quality Marks

Linear Quality marks (LQMs) were applied on the back of meter franked mail processed by an IMP, until 2008 when they were discontinued.  This first sheet gives an overview of the different formats.

LQMs could be at the bottom or top of the arrow ...

... or with the string above the date rather than after it ...

... and in 1996 changed format from having the date in letters to being in numerals.
