I am interested in obtaining a pairs of.....
+ green US test coil tagged.... SCOTT 43..... issued in 1970
+ green US test coil untagged/dull gum .... SCOTT 43c ... issued
I have other US testing material and/or US computer vended postage to
trade or will purchase.
Many of these test coils were sent to Germany by the Bureau of Engraving
and Printing .... so may be more readily available in Europe then in the
Stamps are FUN...but collectors are the GREATEST
