Can someone identify this enfield?

[longtombacon]

I wasn't sure where to post this and I will delete/lock this thread when answered but I just got this passed onto me. Previous owner knows nothing about it. Came with no furniture. Almost no markings. Just wondering if anyone could help me identify this Enfield?



The markings on the barrel say F55 and s23. I was getting tons of different answers by googling those so just seeing if someone here has any idea. Thanks
