Thanks for the year listings, LB1! My catalog doesn't cover the 2008-2009 issues!
I am assuming you want Scott catalog numbers; I don't have a recent SG catalog.
1. #2679a,c,b,d(18Aug2009)
2. #2639c(26Feb2009)
3. #1966(13Mar2001)
4. #2271(24Feb2005)
5. #2241(12Oct2004)
6. #2659(21Apr2009) -- the catalog number is for the entire S/S, you have the strip of 4 from the S/S
Very nice stamps! I have very little recent GB. I especially stamp #2, the Welsh Assembly stamp, part of the Heritage series!
