It's a very straight, very clean No4 Mk1*, Longbranch made, serial number begins 47L, beech woodwork much linseed rubbed by me over the 15 years or more that I've owned it.
2 groove barrel, crisp bore, all numbers match. Comes with pigsticker and steel scabbard.
I'm looking for £400 and could deliver to Newark on the saturday.
My 303 dies and most brass and bullets have gone but I have some 180gn soft point deer loads which I can sell or pull.
Here's an old image which shows her up fairly well; obviously there's the bolt not fitted in this photo and the sling is no longer fitted:
