French Revenues Need More Information

A.O.F OVERPRINTED with no other print for territory name need information and catalog numbers one of them contain value surcharge change

Hello mottaz,

These are French revenue stamps for receipts overprinted for use in French West Africa (in French: "Afrique-Occidentale française" or "AOF").

I don't have any references for these.

thanks dear for your help I knew what you say but I cant find any data online and the catalogs I had didnt mention them

With due respect,
unless your standard of images improves,
I am unable to assist, I am reduced to "Guessing" (colour etc)
So it behooves me to refrain.

The "Timbre Fiscal" are Cat# Type 102 (Billigs / Kremer 1962)
1925 Generally by Daussey
sheets of 50 (5x10)

French Revenues come in a vast array, so correct ID is important.

Remarks:
A large number of Dimension, effets de commerce, Quittances and Timbre Fiscals, were used in French overseas territories..
Overprints made on such stamps by local authorities are not in my reference material.

@rod222
if you need more fine photos I will try use scanner but I think those stamps need no much details to identify any how thank you for your help
