I have a similar rifle, same chambering - but lesser condition and a little plainer: fewer sight leaves, non-ejector, plainer wood - by Webley and Scott, c1906.

Mine behaves fairly well with 82gr 2217 under a 320gr Woodleigh RNSN. In hands before mine, it was a proven NT Buffalo rifle in a well-known character's hands.

I'd be curious for a closer look at the foresight on yours; is that a flip-up moon/night sight? Mine is just a bead on a blade.
