Maybe you guys can help me out, as I think I have an Irish Enfield as well, but I'm unsure.

The markings are:

A crown with "ER" stamped under it.
"Enfield" under that
"1900" under that
"ShtLE" under that
and "1*" under that

This rifle has been sporterized/bubba'ed, so I'm pretty certain it has no collector's value. It does have the floating charger guide, and a magazine cut-off (though I think that is not the original). The magazine is a flush fit, 5 rd(?) steel mag. The barrel has been chopped, and the front action screw head is too big (think it's a mk III screw?).

The serial numbers on the front right side of the receiver ring have been stamped out and new ones added "ER 58-89".

A curious rifle, that I'd eventually just like to sporterize in a more clean fashion (assuming it isn't worth restoring).

Any thoughts?
