Yes. You will need to provide a detailed description of all the markings.
It is usually stamped half-way down the top of the barrel or on the side of the receiver. Some military rifles can be hard to identify because of the lack of markings. My suggestions are to take the rifle to a gun show or competent gunsmith and ask.
Brake barrel rifles are single shot rifles. After each shot you have to fold the barrel down (Break the barrel) in order to cock it again.
Octagan
Rifles and pistols
Literally thousands of rifles. The inside of the barrel has a diameter of ABOUT .30 inches.
Octagonal barrel rifles have several advantages over other types of rifles. Firstly, the octagonal shape of the barrel provides increased rigidity and stability, resulting in improved accuracy and precision when shooting. Additionally, the design of the octagonal barrel allows for better heat dissipation, reducing the risk of overheating during prolonged use. Lastly, the unique appearance of octagonal barrel rifles adds a touch of traditional craftsmanship and aesthetic appeal to the firearm.
Springfield is the manufacturer. A rifle is a long arm with a rifled barrel. A carbine is a short rifle, generally considered having a barrel length of 20 inches or less. All carbines are rifles but not all rifles are carbines.
These were made for the US and Great Britain in 1917 and 1918, but there was no "target model" just standard infantry rifles. The action is popular as the basis for many custom rifles. Check for any markings that may identify the gunsmith who converted your gun.

Do a google search on continential rifles or multi barrel rifle systems.
Depending on the rifle, it may not be possible. Modern reproduction rifles are usually marked with the makers name. However, earlier authentic antique rifles may not carry a maker's name, and may have only a proof mark. Identification will usually start with recognition of the shape and style of rifle, proof marks if European (the US does not have government proof houses) markings on the lock, and markings traditional to a given maker or region of the country. It is as much an art as it is a science.
Markings will be the default answer, though some models have unique features which make visual identification possible, e.g., the Yugoslav M59/66 has the gas cutoff and is set up with a grenade launcher sight and rifle grenade launcher, Chinese rifles usually have a spike bayonet for the basic Type 56 carbine, Albanian rifles have a very distinct look. If you send me an email with a photo and detailed description of the markings (my email address is posted in my profile), I'd be more than glad to identify it for you.
