I have carried out an exercise on the Pembrokeshire contigent of maps which
I think will be relevant to all areas of GB.
If you 'save the picture as' *.gif and then import it into a word processor
which has been set up as a landscape document with 1cm margins, the map will
fill virtually the whole area and is very clear!
The picture measures 184 x 277 mm, this in turn equates to an area of 32 x
48mm on a 1:50,000 OS map. However, do not follow the grid on the OS map
for the old maps are 'offset'!
I have not ascertained the actual angle of offset, forgot my maths!!,
however, a rough guide is as follows.
Pick a grid crossroads. Each grid is a measurement of 20 mm. Having picked
that grid crossroads, move west (to the left) 200 mm then up (to the north)
at that point 8mm. That is the approximate offset.
Now the good news. Each map equates to a measurement of 1 x 1.5 miles so it
should be possible to locate anywhere that you want, as long as it was built
at the survey!
