This list is gradually being compiled as I research the Guinness pages. Any offers of stamps I am currently without are gladly received. The colour coding is:
green for stamps I have:
red for stamps I cannot (or will not) afford - these are only small pieces of sticky, coloured paper, after all;
grey for stamps which don't exist;
orange where further research is required;
text for stamps I need, with Scott and Gibbons numbers and prices from a recent Gibbons Simplified as a guide.

Judging from a recent outing to Philatex , the general approach is to charge 1/3rd or 1/2 catalogue price, which seems about par for the course. eBay tends to be cheaper, FI specialists dearer. I prefer mint stamps, but if there is a significant  price differential will take the used. Stamp mounts don't bother me. If you have any spares which would fill my gaps, please get in touch. I may eventually add my spares to the list, for sale or exchange.
