China Empire Unknown Imprints: Revenue Stamps?

I cannot find in my catalogue next imprints. Are they revenue stamps? Help is appreciated!

Hi Cor, have you looked under the Northern Provinces of China? And yes, they could be revenues

Top 4 stamps
Stanley Gibbons
1941 issue (new York)
section (d)
On type 77 (Scott type A59)
Numbers #95-98 respectively.

All min value 1969

Thanks for that, never seen these before except #96
I had that under Meng Chiang

Tip: A larger scan would have helped tremendously next time

PS: Not imprints, referred to as Surcharges, or surcharge opt.

Thank you rod222, I know the upper row stamps without surcharge () are 1941 New York, but in my Michel catalogue the pictured surcharges are not mentioned at all. I can only find 1c/ 1/2c, 40c/50c (1941/43 Hunan- Guandon issue) and 20c/17c (1943 Hunan issue). So I would like to know what year and what issue the top row stamps are, and if the Michel catalogue has forgotten to mention them!

Cor,
it wasn't easy
I spent some time tracking them down,
But now I have them locked away in my database.

One of the times I have to abandon Scott catalogue,
and defer to Gibbons.
(1969 part 3 America, Asia and Africa)

I usually go by Scott "type"
I can usually crack an ID in seconds,
but these there was absolutely nothing but the 40c Orange
with the SG number.

Not listed in Scott.
A HUGE list in Gibbons

I posted a better picture of the bottom line stamps. Rod222, are you sure of your identification? Could it be they are in the Michel catalogue mentioned under Central China? But even then I see no clear reference.

Hi Cor,
No
I am often wrong, that's how I move forward.

These can be confusing, but this is how I read it
The basic stamps are Dr Sun Yat Sen
Scott Type A57
Stanley Gibbons Type62 apologies Typo Type 72

The Surcharges on these, the FONT (FOUNT) indicates they are of CENT values

Thumbing through Scott, I came to the conclusion they were not listed.

In Gibbons this is what I found 1969 Page 147
Seems to fit?
Gibbons #415 #416 #418 are the basic stamps of you surcharges

Perfect, thanx so much!
