1st class red Security Machin forgery.
Several types which have been produced, this listing may be for variants of the same one, or be three different!
Coded M14L MTIL -
36-38 Slightly glossy, with a very rough finish
58 Glossy, with text very clear - three on piece with cds
The phosphor does not react to UV light
NB Some of these forgeries are difficult to distinguish from each other, and I may have listed as different stamps which are in fact the same type as identified by the Modern British Philatelic Circle or others. If this proves to be the case and you wish to return a purchase, please email first per our Terms and Conditions, so that we can discuss.
