Uruguay Perf Varieites

I am sorting this country in the 1890-1920 period, and there is a huge seemingly random spread of perforations, many mixed and not very regular. Are these philatelically significant or just completely random? I've got a good eye loupe and nice perf guage, but these are small perfs (mostly 14-15) and many are poorly done, either not straight or uneven across one side. Scott is not specific on this point, only using the range of gauges as a header.

BTW, resources of Uruguay seem sparse, any tips? My Spanish is 7th grade-level, but I can read charts and tables in any language!
Thanks
Dave

Gibbons's South America is the other English-language catalogue, but s currently being revised. My edition is quite an old one. It too gives ranges for perforations, rather than detailed breakdowns. Yvert does a South American catalogue, and Michel ahs a two-volume edition. Haven't seen those.

Thanks for your reply. My Michel does not itemize them. I don't have an Yvert for South America. I'm hoping there is a book or article somewhere that goes over this.

These were right after the rouletted stamps from the 1880's. I am thinking that whoever printed these for Uruguay was either learning how to work the machine (doubtful as the results are spread over a 15- year period) or they were stuck with a broken-down or poorly made machine. Many of the perfs seem to be not in a straight line across the edge and actually seem to be "broken" in the middle of an edge, i.e, the holes are regularly spaced, but in two "segments" that meet in the middle. I'm getting a headache measuring them. This makes me want to scan them and measure them that way, but that is just as tedious.

Some tips :

Cortado en linea = roulette
Variedad de dentado = perforation varieties
S/D = imperf.

Dave, I hope you'll scan a few examples for us. Uruguay was forced to print some of their stamps in country because of many difficulties, not excluding the misunderstandings and incompetence (?) that rose between it and American printers. The best work was to be had from England. Many of the early stamps in this period were horizontally or vertically imperforate.

The Uruguay specialised catalogue is a fantastic resource. Thank you.

Wonderful, jorge!

Dave, 'cortado muy desplazado' means misplaced cut and 'dentado muy corrido' means perf misplaced. (For 'corrido,' I think this means that the perf runs right through the image in a dramatic way. Perhaps jorge will confirm this for us.)

KGB, you're entirely right in what you say

Jorge thanks for that link. That is very helpful. I am looking forward to getting back into this.

It's Thanksgiving here in the US and I'll see if I can get some scans for you later today or tomorrow. Now I'm off to dinner with the family.
