These marking usually indicate it is a training rifle and is the name of the school.
This was either made as a training rifle (bore has no rifling=do not shoot it) or a previous rifle removed from service and used for training. If it is rifling, you should be able to shoot it after inspection.
If you post pictures of the receiver markings (top and left side) it will provide more info to help ID the rifle. Also check for barrel rifling.

Oh, based on the rear sling swivel, it’s a Type 38. There should be two holes on top of the receiver chamber.
