P&R I 10c Rivadavia Brown

Mensaje por rubiera »

I have spent some time grouping this value, that may well be the most difficult-to-type value of this series. Here I show the first clay paper issue on reddish brown, the CL1A, from 1939; and the second clay paper on dark/blackish brown, the CL1B, beginning use in approximately 1941.

I do not coincide with the information I came across in an article by the proposer of this series, Tenorio, who mentions that the first printing was on offset and was placed in circulation March 16, 1939. Tenorio mentions that the first clay typographed issue was placed in circulation November 4, 1939. Tenorio mentions that the offset issue is rare, and I do not find it. This is what I find:

I find the CL1A cancelled May 1939.

I find it as an official issue overprinted "Servicio Oficial"

This stamp is less common than most other 10c Rivadavia Browns, but this is relative rarity since these stamps saw heavy use. I only find one cover with this stamp, dated August 20, 1939:

The differences between the CL1A and CL1B clay papers is minimal. The sun for the CL1A is slightly larger than the sun for the Cl1B; the CL1A is flatter, and the CL1B is thin and shows the watermark in relief.

The CL1Bs are slightly darker and show more plate wear. By 1941 the plate shows dots of wear that show up throughout the design as a grid.

I find it on over, but it is not common in this format:

The first offset stamps I find are from 1941/42 and type A (round jacket). All are red brown. The regular issues seem to be printed on the 1E3 paper:

The officials also seem to be printed on 1E3 paper, but this paper is thicker and the watermark is somewhat diffused.

Imagen

Imagen

I find a darker shade of this stamp in 1946, but only on the officials:

Imagen

Imagen

And I find the regular issue dated 1949:

Imagen

Imagen

I need to continue to look at these offset issues to verify how many distinct issues there are. The main question is if the stamps dated 1946 and 1949 are separate issues or late usages of the 1941/42 issue.

This watermark is the easiest to distinguish for the whole series:

The regular issue is usually found with a worn impression. All are type A. There is a wide range of colors. I include three here.

For the officials, I find two significantly different colors:

This stamp seems to be rare. The paper is thick and the perforation usually faulty. I only find officials for these. All are type A.

This stamp is only found as type A, on paper CL2A. I do not find it as an official. These have a horizontal-running watermark.

The following strip has an unusually clear impresion.

Imagen

This pair has a peculiar shade and comes from a relatively clear printing.

Imagen

This is the most common shade for the horizontal watermark stamps, and shows the typical significant plate wear found for this printing.

Imagen

This is an exotic color, brown black.

These have the watermark running in the vertical direction, are also type A, and not found as officials. It seems like a different paper when I compared them with the horizontal watermark specimens. I need to look at these further.

The first printings on the 1L papers, from 1951 to 1953/54 are all of type B.

On the 1L1 paper:

I am still trying to figure out these red brown stamps. They are type A on the 1L1 paper and may be a separate printing.

This stamp may be the equivalent to the one I refer to as 1E3 from 1949....more work is required here.

I find a few of these, all type B, and only on the regular issues:

I used to refer to this stamp as a "small die" type, but after measuring it, I have realized that the worn impresion, probably from an acid bath applied to the plate, makes the stamp seem smaller than it is.

Tony,

judging from the scans the first stamp is a Holandés [1E4] - see the symmetrical paper wire and the horizontal direction of paper; the second a 1E3b or a 1L1 - see the asymmetrical paper wire and the vertical direction of paper.

The Dutch paper first appeared for the 10c in 1942! But S.O. stamp may be found much later! The 10c type A also exist on Dutch paper just by itself!

Tony,

all the typographed 10c stamps you display here belong to type IV - with the "L appendix"! They can have 4 different types of paper!
Types of paper and their first use [according to Pettigiani] and their relative scarceness:

TI 2 1942 normal "c" for both; This should be closer to 1945!
TI 3 1950 ascending "c' for both; descending "R" for both
TI 4 1949 ascending "c' for both; descending "R" for both
TI 5 1950 normal "R" for both; inverted "c" for both

Pettigiani mentions the design sizes: 26.8x20.3mm for the first printings [TI 1 and TI 2 partly] and 26.3x19.8mm for all later ones. My impression is that the 26.8x20.3mm goes with the types II/II and that type IV goes with the 26.3x19.8mm.

Brown fibers are found so far only in the medium sized commemorative stamps! But we also have some P&R I values:

This is the 10c Rivadavia in offset-litho, chestnut-brown in type A! Wiggins Teape paper with a parallel watermark and a symmetrical paper mesh! Density 24/22 AKA "Tela"!
