Blucher Sabre?

The blade markings are French, but the hilt is germanic. I guess the blade is from a captured 1822, that has been rehilted at some point.

Well noted Madnum.
The M1811 Blucher Sabel was designed after the British M1796 light cavalry sabre, and remained in use for many years, with the form carried into later models of stirrup hilt swords used by the Germans.


The use of what is clearly a French made blade seems unusual, but hardly unexpected in extended use of these swords. The markings on the guard of the hilt and throat of the scabbard reflect such extended use.


The RAMK likely are for Reserve Artillery Munitions Kolonne and a unit number, the last numeral a rack number. The cancelled RA would be probably a reserve artillery unit. Again the far right a rack number.

The R.A.M.K. stamp is from the times of the First World War documenting how long these sabres have been in use, the cancelled stamp however is of the Reserve-Artillery Regiment N°6 between 1870 and 1914.
But the both "R"s are written in a different style. Normally the "R" in italics stands for "Reserve", the normal "R" however should stand for "Regiment". So the "R.A.M.K. 15" should be red as Artillery Regiment N°15 Munitions-Kolonne.

Corrado, thank you for the further insight into these markings, I was using my trusty 'Hughes & Fox' which is comprehensive but very cursory. Your notes further reveal how incredibly long these weapons remained in use.

This is not a Bluecher cavalry sword, but the Prussian Artilley Sword n/A, its scabbard just has one fixed ring whereas the Bluecher has two movable rings
