Can anybody help identify an old Steyr?

[point and laugh]

I have a rifle with the interlaced I and C below a crown on the top of the receiver (Portugal).
It is marked M1892 6.5x53 and STEYR 1899. It has a 3 digit serial# preceded with a D.
It is the bottom rifle in the pic, below the pair of 1917 Steyr-Mannlichler M.95's
Any help will be appreciated.

I'm leaning toward it being a mannlicher-schnouer and it could be greek issue.

Its dutch or romanian as i suspect. A little bit of info on the 6.5X53

If this ammo is a rimmed round as I suspect it's 6.5x53R Dutch Mannlicher.
It was designed for M1892 & M1893 rifle and was used by the Dutch and by the Romanians.
It has similar power to the 6.5x54 Mannlicher Schoenauer and is a handy little cartridge.
I believe the factory specs are the 160gn RN at 2300fps.
Like the other true 6.5mm/.264" military cartridges 6.5x55, 6.5x54 and 6.5x50R Jap it is a low recoil high accuracy cartridge whose performance on paper belies the fact it's an efficient and highly effective killer.

Lil more info

Both Dutch and Romanian rifles fired the same 6,5 x 53,5mm bullet often referred to as "Romanian" or "Dutch 6.5"
