Still on the theme of stamp collectors and their contributions towards the hobby in the past, I have this to say.

In all my years of stamp collecting (60+) I have never known British stamp papers to have been so contaminated before (or since), normally unseen by the naked eye but very prominent under the relevant ultraviolet light, similar to phosphor band tagging and their variations.

The fact that the FIB's discovered are so different beggars belief as to why there has never been any previous write-ups in any magazines or other philatelic publications in the past, does nobody do any research or study on Wilding stamps anymore ? Or do they just follow the herd ! Added to the fact that these stamps have been in the hands of collectors now for over 50 years.

Much has been written on the subject of Machins to the point of exhaustion (which is commendable), but their predecessors have been treated as a Cinderella.

How can stamps with such an identifiable difference be ignored !img_20200404_133649.jpg

Although there is a slight duplication on some of my scans between in this thread and the CREAM Vs WHITE one recently updated, I feel that this posting should join its partner to be read in conjunction on the subject of stamp papers that appears to have been neglected for so many years, thank you, Fred.

To discover a stamp that is not listed in a specialised catalogue can be quite a thrill and this seems to be the case with several of my findings over the last few months, and all due to a longwave ultraviolet light used. This next find also gives credence to that fact.

The majority of experienced philatelists will already be aware that the non-watermarked papers of the late 60s and early 70s registered a high fluorescence when subjected to a long wave ultraviolet light due to the type of paper used, classified as being coated by catalogues, but it would also appear that some of the watermarked stamps of the late 60s period have similar attributes but have been side-stepped (for want of a better word) by catalogues.

This next discovery involves the 3d plain originally issued for Wales on the 18th of August 1958 originally printed on a cream paper, later being changed to a whiter one in 1962 attributed to the filtration of the water used to make the paper, followed by the centre violet phosphor band using a similar paper issued on the 16th of May 1967 concluding with the no watermarked coated paper on the 6th of December of the same year.

This find involves the 3d Welsh regional stamp (plain) printed on a highly fluorescent paper that reacts in a similar way to the no watermarked papers and could be easily mistaken for one of them, this is clearly not the case as this paper has a watermark embodied into its structure as can be seen in the scan below, followed by a scan of the same stamp as seen under longwave ultraviolet light alongside a cream paper to the left .

Very few specialists will have obtained this stamp in their collection, so keep an eye open when visiting stamp fairs or stamp shops that you frequent for this little gem !
