When ever I buy a job lot of counter booklets is always nice to pick out panes with marginal markings to study. There are several that are obtainable which that can be found in most counter booklets. Panes for these books were made up from a original primary sheet of 200 which contained 20 rows x 10 columns.
Each primary sheet can have left or right marginal panes catalogued either A or B. Some of the panes will therefor have marginal markings. These markings can show cut lines, top and bottom, or in the centre if they have been miscut. Other markings can be half arrows either top or bottom, Other markings can show the wording total sheet value in capitals and value of the total sheet amount in £s. We can also find cylinder numbers in row 1 or 2 of the individual left or right panes
Another collectable pane one of my favourites is that which show colour registration marks, these are in what collectors have called in the shape of triangles or chevrons. These are something just a bit different to the norm and make cheap attractive additions to a collection.
A couple of booklets showing the triangle /chevron markings are shown in the pics below.
0.80p No1 SG FE1B Aircraft series (DB2B 1914 and Vickers Gun Bus
£1.00 No1 SG FH1B Ironbridge from the Industrial Archaeology series
I have these and a few others that are duplicates and are surplus to my requirements so they will eventually all go for auction on my eBay site. If you like what you see check them out.
