Another barely credible 1st class forgery

The last 1st class Machin forgeries found locally are easily indentifiable by their odd die-cut 'perforations'.   Now Dave Allwright has shown us another which is notable for its abbreviated form of face value:

 

Incidentally Dave also points out that the die-cut on these and the earlier ones looks very similar to some Isle of Man stamps, although not the same size and format.
