Identification of uniform

[lissatrena]

Hi,
I am looking for someone who can help me identify the uniforms
in the photo. I came accross this site by pure coincidence and would be
greatful for any information I can get.
We believe the picture was taken in the early 1900's. We think the one sitting
is an officer. We think they are Russian Navy, but we are uncertain.

Thank you,
Lissa

For sure this is Imperial Russian musicians, both in the rank of NCO's. But not a navy.

Thank you for getting back to me so soon. I appreciate your

As well they are not cavalry, and not Guards. More likely these are NCOs from Infantry or Rifles regiments, but not enough information visible to say for sure.
Unfortununately they don't wear belt-buckles which could help to ID the branch of service, so we can solve the problem by two ways:
1. Check the Russian Army unit locations to find which units were based in cities of Prasnish and Noviy Dvor.
2. Need hi-resolution image of shoulder-boards of these soldiers to read what is inscribed on them.
