UNCOATED PAPER ON 4d BRIGHT VERMILION

Are all examples of the 4d bright vermilion from the Stamps for Cooks on uncoated paper and if not why some and not others?

Hi Mike,
On the topic of coated papers I have examined several values other than stamps for cooks book, and noticed certain other values appertaining to this anomaly the like of which can be seen in the following scan.

The 2d+9d values appear to be non-coated whilst the 8d duck egg blue appears coated.
I also looked at some of the earlier QE ll commems that first appeared on some of the 3d GLO of 1960, the coating has been applied to the printed side of the stamp, leaving the reverse untouched as can be seen on my next scan of the 1961 parliament stamps.

I may be wrong, but the pre-decimal Machins appear to be coated also on the gummed side, were they printed on a coated paper, or a Chalky paper and possibly even a reversed paper ? WM.

As far as I know (caveat -- not my specialised subject) all Machins were printed on coated paper except in error (which seldom happened) -- and this was the same paper used for the no-watermark regional Wildings?

Hi MOZ,
I am in full agreement over the similarity of papers used for the un-watermarked Wildings and the pre-decimal Machins, however, that is not the topic ! But to compare similarities/differences between the same issue for my posting on the subject of coated papers.

Here is another example of what I have observed, note the difference of the 9d's as seen under long wave ultraviolet light.

Would you say that they are identical ? WM.

That's an interesting one -- a clear difference. Deegam lists dull and bright fluorescence versions of several pre-decimal Machins, but the 9d isn't one of them. There's no 9d uncoated paper recorded either. Are these the same gum type?

Hi MOZ,
The vertical pair are gum arabic, but the block of 4 are PVA, I am not a specialist in the Machin issues and do not possess a Deegam handbook, please bear that in mind. Thank you WM.

Interesting -- now I check, the dull/bright fluorescence variations listed for other pre-decimal Machins don't seem to be correlated to gum type. So this may be something unrecorded.

To answer the original poster, btw, not all Stamps for Cooks panes are on uncoated paper, but as far as I can see all the 4d uncoated paper stamps are from the Stamps for Cooks booklet.

It would appear MOZ that you have a much greater knowledge on the subject than I. Perhaps you could let me know the outcome once you have investigated further. Thank you, WM.

I'm no Machin expert -- but I needed to dig into them a bit for some articles a while back, hence I have the specialised catalogue (much too specialised for me, usually).

Hi MOZ,
It's quite possible that the editor of the handbook Hanns Fasching might be able to give you some information that you are seeking, I can't guarantee that you will get an answer as he is rather a busy person, but being Machins I'm sure he will try and help you rather than search for previous articles on the subject, his email address is :-
mbpc.catalogue@kabelplus.at

It's at least worth a try, by the way I have further inspected the 2d 2 band PVA's and have found that the same difference applies as with the 9d GA & PVA, therefore the difference is not gum related.

Here is a scan to emphasize that fact.......

WM.
I have further updated the original scan of the 2x9d's and the 2d PVA one to clarify the matter !
IMG_20200521_170053.jpg
As this one now denotes the gum type.

I have also discovered to my amazement that on some of the decimal Machins within the paper used to print them, they appear to have some form of contamination, in the form of fluorescent particles/fibres similar to those found on the earlier Wilding multiple crown issues, please see the following attachment as seen under long wave ultraviolet light :-

Although I am currently not studying Machin papers they must be of interest to the specialists that are. WM.
