Hi there, I have a 1c green Franklin stamp on an American postcard dated April 2nd 1915. There appears to be a watermark S, possibly with 1 line or double lines. 10 perf along top and 12 down side. Franklin's neck is distinctly scalely looking, also shows a whiter line to base of stamp. Could this be an elusive DW61 ?
no. 349 A.
