Hi there, just looking for some help from anyone who can offer it.

Spent a lot of time trying to identify this rifle, but now I'm at the end of my identifying abilities.

Could someone tell me specifically what I have here?

I have a few issues, i thought this may be a boy's carbine, but not sure.

IT has the "K" stamp on it, with "1901" below that, and the Serial "5799" below that.

I'm confused if this is an original boy's carbine, or it one that was taken apart and reassembled in the 40's or so, with different matching parts.

Not in pic on the barrel there's another stamp that I've drawn a picture of (as best as i could).

Thanks for any input!
