Hello, perhaps you will enjoy seeing this from a 1989 booklet sheet.   In my view it is always worth looking out for these at stamp fairs and club tables because you can find a few of the more difficult to get Machin phosphor band variations from them.

 This one is the Scotland issue, SG S55l in the SG Concise catalogue.   One stamp in particular I will point out is the 23p value; the bright green one, which is listed as SG S68 with a catalogue value of  £12. I point this out because it has 2 phosphor bands, and the more normal counter issue SG S67, also bright green which is on phosphorised paper has a catalogue value of £1.10. Perhaps worth checking your Scotland 23p stamps if only to make sure you have both in your collection. And, so you don’t accidentally swap or trade a 2 phosphor band stamp without knowing it!

The phosphor bands should be easy enough to see under normal light but with the ultra violet light they show up clearly. Well I tried to picture that in the image below.You can see the two phosphor bands running from top to bottom of the left vertical line of stamps.  You can also see the left bands on the centre and right vertical strips. 

This booklet sheet with a lovely Inverness first day of issue cancel also contains  2 x S55 (the 14p dark blue value – actually this also has a  different phosphor band to the more normal issue as well;   2 x S63 (the 19p value, again 2 phosphor bands instead of phosphorised paper as found on the more common issue) and as I mentioned the S68 23p bright green with 2 bands. All in all a very useful booklet sheet to look out for I think.
