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.

Literally thousands of rifles. The inside of the barrel has a diameter of ABOUT .30 inches.
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.
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.
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.
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.
If there is a serial number, it should be conspicously marked on the receiver. Shotguns and small caliber rifles did not require serial numbers before 1968, so many do not have one. If it is a break-action single shot or double barrel, there may be additional markings on the bottom of the barrel(s) and on the flat parts of the action that the barrel covers when the it is closed. The Hercules brand name was used by Montgomery Ward on guns made by Iver Johnson and J. Stevens.
No way to answer without pictures and all markings.
