Doug, I am now able to tell you that your 1/2d JIPEX  sheetlet is No. 6 of 10  and the 1d is No. 16 of 21. So, if this were to become your collecting field you still have some way to go. However, these JIPEX Miniature shets are not difficult to accumulate. Apparently the 1d No. 7 is the difficult one. 

This breakthrough is due to the generosity of a SAPC member who has provided a full listing of these different JIPEX  panes. I will soon post it on the SAPC site under a new heading, hopefully as a display in its own right. In future, all visitors will be able to determine what Panes they have. Great! Many thanks to Bas for making this possible.
