Cancellation On Rhodesian Stamp

Is this really a cancellation and not overprint? I never saw such cancellation.

It's not a postal cancel. It's a fiscal/revenue cancel.

So it was used to change the stamp from postal to revenue? The stamp is already declared postage AND revenue.
I guess you mean that when used as revenue, that is the cancellation it got.

No, it did not change anything about the stamp. It was used as a revenue stamp like most other British stamps that are both revenue and postal stamps.

oh. ok. Thanks.

Yes.

Well, it changes the stamp in terms of the catalogue and of the catalogue value, which is for postal use. A fiscal cancellation means that, in catalogue terms, it's no longer a postage stamp. The value will, therefore, be lower. Except, perhaps, to revenue collectors, of course!

I lack knowledge with respect to revenues. Has it long been a convention and consistent that revenue cancels are of a color different than black and that all/most postal cancels are black? Or are the conventions more country-specific?

In general, are ovoid cancels likely revenue cancels?

Not really. Revenue cancels can be any color, any type you can think of. Even a signature and/or date can invalidate the stamp.

I agree with Peter. It's hard to generalize with postal vs. fiscal/revenue cancels. Great Britain and colonies registered mail cancels were oval for a long time.

It helps to be able to read the cancel if you can. For New Zealand for example, "Stamp Office" in a cancel means fiscal/revenue usage even though it may seem to be some kind of postal usage.

Thinking out loud: I wonder if "P&W" stands for "Pratt and Whitney" ?

Example of stamps with a signature

Example of 3 postage stamps of Dutch New Guinea with signatures.

Unfortunately only a fragment of a document, but very unusual as revenue stamps were avalaible in New Guinea a that time.

Purple cancels on commonwealth stamps are usually a good indicator of fiscal use. Not sure how common the 6d is with fiscal cancel but this is what makes finding the high values like 10/- and £1 stamps with genuine postal cancels so difficult.

Rod - you mean it? Where there P&W factories in the 60's?

Indeed I do.
Stranger things have happened in Philately.
Circa 1935, you need a company significant enough to have a dedicated canceller.
There were no factories, however Pratt and Whitney had service centres globally for their aircraft engines.

It is a huge long shot, but you never know.... Googling......etc

Most of the order went to Southern Rhodesia. A second batch of ... Pratt & Whitney Wasp R-1340 radial engine and served from 1940 up to 1946.

I googled, maybe not thoroughly enough, and didn't see a connection or mentioning their factories in that area.
But I've learnt enough: A revenue stamp with revenue cancellation.
