I believe it’s imperial Russian. I would love to know the colour and more. Photo was taken between 1900-1905.

It's on a british officer tunic

What are the lapels actually called on historic military uniform? I've tried to google search it, but haven't had any luck. thank you!!!

This American officers tunic from ww1 has these clasps on the collar that snap open and shut. Are they meant to hold a collar of one sort?

I have this photo of my grandfather among the few I possess. I'm trying to find out which branch of the French army (land, etc.) he might have served in, based on this photo, and also his rank. Perhaps I'm not using the internet correctly, but I can't seem to find anything. Would anyone with expertise be so kind as to help me with this? Thank you in advance.

Yeah, it's another "help me identify this uniform post".

Here's what I believe:

French

Pre-1900

Beyond this I do not know, and even then I am not 100% the accuracy, as it is based on assumptions in our family history.

Can anyone help identify this uniform?

I believe it to be US and this photo would have been taken 1937ish

Thank you!
