Type "F" is the so-called "rayado vertical" or simply a parallel watermark like "A" which had a symmetrical paper mesh. This onje has an asymmetrical paper mesh. As it comes from the same manufacturer - Wiggins, Teape and Alex Pirie [Portals in the mean time?] it probably had the same dandy-roll used but with a different wire! Or maybe just on a different paper machine? Pettigiani claims it is a "papel mas complicado"! Why??? One reason is the chronological spread: 1944 - 1950/1951 -1956.... That is a bit cryptical! The 1944 part is relatively easy as several face values have been found with early dates [1944/1945] and the asymmetrical paper mesh - the 25c Labrador and the 50c Petroleo for instance. Apart from that the 17.02.1944 Earthquake stamps - the only "commemorative" in a period where most had "Tela"!!!! 1950/1951 is probably the period where we more generally found this type of paper! But 1956??? The 1947 20c Antartida stamp is referred to [MT 486I] as the earliest one, bu bear in mind that also Rayos Rectos occurs for this stamp so we need to know precise dates of use! With MT 505 were are amidst the 1950 San Martin commemoratives of 1950! MT 564-566 the 01.09.1956 Provincialisacion stamps are certainly not the Last of the Rayado Vertical :) |

| ... How does Papel Rayado Vertical look
like????
[quote]
- the black line indicating the direction of paper - the blue lines the virtual diagonals of the mesh - the yellow triangle formed by the hearts of 3 suns - the red line the distance from the heart of the suns within the line of AЯ - the green line the distance between 2 identical lines of AЯ - the violet lines the diameters of the Sun -
This paper is named by various authors as follows: Rubiera 1E3b and 1L1, Bardi MI 5 [/quote] The various subtypes of the rayado vertical certainly deserve a more detailed study which should include good scans to everybody will know what to look for! Just separating the "trama difuso" or "trama cerrada' as paper F" is maybe a but simplistic.... |
