Hello, one more from my sorting tonight.   Interesting that this is the 15c stamp which in 1953 was the first QEII stamp to be overprinted STAMP DUTY. 

This one is also overprinted, as you can see, B. of E.  That is Bill of Exchange.  I have no more knowledge of this stamp or other Revenue Stamps from that period so if any reader can educate me I would be most pleased to hear from you.

Hope you are enjoying your stamps

Best wishes..Michael
