1 1/2 D - Os

Hi,

Do you know what is OS (perf) on this stamp. I think there are some stamp like that with "rough" paper... but i'm not sure. Maybe you know how to identify "rough" paper...

Thank you!

'OS' on Australia King George 5 (KGV) side-face stamps means Official Service.

This would be similar to O.H.M.S. perforated initials (perfins) on Canada stamps. (On His Majesty's Service).

Used for stamps being used for government service only.
I am not sure if there are different variations of these perfins. For Canada I am just learning there are many variations plus fakes made also.

KGV_Collector's thread on these stamps is the best explanation of these I know of.

Hi Puzzler,

Thank you!

This stamp was never printed on the rough paper. The 1½d wasn't printed in red until 1924; the 1d red on rough paper appeared during WWI, in 1916.

However, there is an inverted watermark recorded for this stamp - £20 used in the current Gibbons.

Hi Tonymacg,

Maybe this one is "rough" paper because irregular perf ?

I'm not sure but look is different...

Thank you!

I have a good friend who is US Secret Service Agent.. I tease him about being in the "SS".

cdnum rough paper is very coarse mesh.

Please correct me,if need be, but the 1924 1.5d single wmk scarlet
was printed on rough paper.

I only see a mention of 77a, very thin paper...

I don't see a note above or below the listing that would say otherwise regarding rough paper...

[edit: I'm guessing the note I would be looking for would be similar to the note for the 1.5d green printed in 1923 on rough paper (SG#61a).]
