Argentina Specialized Question

The 1892 definitive issues of Argentina include two distinct colors of the 1/2 centavo stamp. A dull or gray blue that's quite common and a much more intense ultramarine that's also much harder to find. Guillermo Jalil's 2002 catalog list both colors in the default perf 11 1/2, but not in the less common perf 12 1/4 or the compound perf. I can't find my Kneitchel but when I put my pages together initially I left the ultra out for the two perf varieties. I now have an example sitting here that it the bright ultra and perf 12 1/4. Is it a new find or did Guillermo just leave it out by accident? I don't have his new catalog so can't check to see if it's been added, and he's usually very good at listing everything.

I'd be interested in seeing scans of the particular Argentinian stamps discussed. Thanks.

Are you talking about. GJ.190 perf 12 1/4? or GJ.205 perf 12 x 11 1/2
GJ.190, ½c. Azul fuerte. What is the shade of blue you have ?

For all the new collectors here ,this is the stamp being discussed , From my collections ---

I'm talking about GJ.127A and GJ.152, the 1892 small sun watermark. Here are scans:
Perf 11 1/2

Perf 12 1/4

Are you sure your perf. 12 1/4 is a small sun ?

That did it, I hadn't checked it to make sure the paper was right. It's the sol grande indigo.
