Description
Machin U134 Marginal Pair Experimental 4½p
Issued 13th November 1974.
Printed by Harrison & Sons Limited in photogravure.
The colour is grey-blue.
Stamps with normal phosphor bands were printed on phosphorised paper as an experiment and issued as above. Bear in mind that the phosphorised paper is not noticable in daylight, but the whole stamp gives an ‘after glow’ under a short wave UVL. They were only on sale until December 1975.
The paper is phosphorised (FCP). Also the gum is poly-vinyl alcohol dextrin (PVAD).
There are two phosphor bands.
Stanley Gibbons Great Britian QEII Specialised Volume 4 Part 1 catalogue number U134.
The Concise (2019) catalogue does not list this example.
These examples are from cylinder 7 dot phosphor 17.

INFORMATION SOURCES:
First of all, stamps will be well packaged and sent by Royal Mail. Therefore please see our Shop menu for postal options. Postage
Also we only charge postage for the first item in most cases. Thus any further items purchased would not increase the final postal charges. Furthermore we do not charge you for envelopes and packaging.
Recorded Delivery or Registered Post is also available if required. If one of these options is taken, compensation for loss or damage can be claimed.
We mention Stanley Gibbons catalogue numbers where it is possible. These numbers are either from the “Concise Stamp Catalogue” or from the “Specialised Stamp Catalogue Volume 4 Part 1”. We will try to mention any other numbering that we may use if not covered by the above. Sometimes particular stamps, Smilers sheets, booklets, miniature sheets, or cylinder blocks are not recognized anywhere. Hence, in this case, we would use our own expertise to describe and value that item.
In conclusion, all of our stamps are unmounted mint and also in an excellent condition. We will mention any variation to this statement.
Please let us know if we have made a mistake with this description.
