Russia Cover To Switzerland

I'm looking for somebody who can translate the Sender postmarks on this nice letter from Russia to Switzerland 1873, appreciate your answer, thank you

The CDS at the top left is a Russian railway postmark - it includes the words "POCHTOVIY VAGON" ("Postal Wagon") in Russian.

The important information would be the pair of numbers which follow "VAGON". These would identify the route being used.

The boxed FRANKIROVANO mark in Russian simply means "franked".

The boxed transit mark with the bold 5 was used on mail from Russia to Prussia between Katowice and Breslau.

The full mark would read:

AUS RUSSLAND
EIS:POST BUREAU V
19 5

where "19 5" is the 19th of May.

Thank you for your contributions Nigel.
Don

many thanks Nigel for your detailed answer ! Peter

Peter,

the TPO (Postal Wagon) postmark is from line 21-22, i.e Kiev to Odessa.

The date of posting is the 5th of May, 1873. The month is given in the second line of the date, in words. The first line of the date has 2 numbers: a "16" and a "5". The "5" refers to the month (May), while the "16" refers to to the number of the railway station along the route at which the piece of mail was collected.

thank you very much Vasia for the very interesting explanations !
