Late answer : Yes

Hello Gentlemen : The man on the photo wears a interwars uniform , very smart , he is not an officer but a career NCO ,entitled to use a Sam Browne belt without the shoulder bandoliere. the dark patch could be Cavalry ; Dragoons , Cuirassiers ,Hussars Or Chasseurs .but also Engineers. the colour of the uniform is probably bleu horizon and judging by the apparent length of the tunic skirts the date is around 1930 .

filfoster : into the page Gradi del Regio Esercito Wikipedia In Italian exists the colour plates 

GreyC : Its hard to say . the mostrina (collar Patch) is not visible . shoulder boards also not are carried on the Pastrano (coat) A closer view of the cap badge may help.

filfoster : The colour called Hechtgrau was adopted by AH for a new field uniform in 1908. It was no a newcomer .really was and old one .it was the colour of the Rifle regiments and Bataillons since the Napoleonic Wars.and originally was a medium grey with a strong blue tint .but always the exposition to the sunlight faded the tint and yellowished (sic ) the colour so appears greenish , an Austrian collector and fisher said me that the same occurs with the pike fish when caught and exposed . The Army Museum in Vienna shows many Pike grey uniforms . those in mint condition are openly light blue in tone but others ,with signs of wear are more light in tone and a bit greenish. An american reporter who saw the German Army in Belgium in 1914 and the Austrian Howitzers deployed there says in his reportage Austrians with silvered ! colour uniforms . Its a matter of light and another facts .

Kriegsmarine I suppose .but why the lace on the shoulder boards is blue and the SBs itself are gold?

Ah Ja ; es ist klar . clear as water,.

Hello . I think that the tunic certainly is for a musician .but its not Swiss. Its much British in Style an even manufacturing.

Chris : Thanks again . by way of simple curiosity, Anyone is truly sick ?

Superb display Chris , Thanks for share. a question : the mutze with carmine band and piping is of a GS officer? or perhaps of a Chevaulegers Regiment ?

Interesting ¡ Once I read about the China Marines a force very special with mounted Marines inclusive.

Nice posts Morar Andrei.

Well , solved  my mistake.

Hello : The Prussian , Yes Sir ! . Ostuf , The three men in the first pic (ampliation ) are from left to right, Prince Boris , General Jekow and General von Steuben. its curious the use of tropenhelme by the Prince and another Bulgarian officer.

Von Roques Maumont is a nobility family of French origin . one branch via Switzerland settled in 1760 in Celle and their members provided officers to the Elector of Hannover

Lieutenant general Nikola Zhekov (1864 1949 ) was first  minister of War in 1915 and then Commander in chief of the Bulgarian Army (oberbefehlshaber) from1915 to 1918 due to the fact that King Ferdinand I resigned his prerrogatives and appointed the General

Hallo : I read the same as ixhs Oberbefehlhaber etc . but the manner in which the name of the bulgarian general puzzled me .commonly the name of the bulgarian Chief of Staff is writed as Jekov or Jekoff . even Schekoff.must be him 

Ostuf : The German 11th Army when was deployed to the Balkans with HQ in Prilep . was commanded By General der Infanterie von Winkler and later by General der Infanterie Kuno von Steuben . The name number 2 appears to be Bulgarian . 

Yes Sir ! and a British one . not a Putilov

Thracian : The badge is not Indian . Its Canadian from the Highland Light Infantry Of Canada .observe the maple leaf in the center , the scroll and the beaver.

Like I said before, in the war several cavalry regiments were raised with those high numbers; some of them became Kavallerie-Schützen-Regimenter. KSR 93 was dissolved in 1918.

In the ranklist of honour is a Lt. Werther named in württ. Dragoner-Rgt.25. He ended the war as Rittmeister a.D.

Lt. 16.6.10

Olt. 18.12.15

In the list of 1919 he still was Olt.

I don´t know if he is it...

Its possible , wurttemberger officers were interchangeable with prussians . 

Ostuf , Thanks for your answer . as i suspected ,the regiment 93 was not a common one . The Kavallerie Schuetzen Regiments were dismounted Cavalry .the German Army began in 1915 to employ cavalry in the trenches and in 1916 to dismount regiments .then appeared a new type of Cavalry the Cavalry Rifles . their regiments were of bataillon size , three or four squadrons ,equivalent to infantry company in number and a Machine Gun squadron with 6 Mgs and four minenwerfer . apart ,normally the regiment possesed also a mounted platoon of 25 men . The 93 K S R judging by the number was a unit raised from the 93 kavallerie regiment which was a war raised unit . i will search about the 93 .to me it was a Landwehr unit .

Ostuf , To me is also Werther but what is strange is 93 kavallerie regiment . doesnt said anymore ? Landwehr Reserve or Schutzen ?

Dante : The 9th JzPferde regiment was deployed in Ukraine between May of 1918 and the Armnistice.After a slow retreat returned to his garnison in Insterburg in good order the 22th of Februar of 1919 . then it was disbanded . If the FreiwilligerBtl was organizes in Insterburg probably the JzPf was the base
