The No.4 Mk1* were a design modification on the Bolt and receiver to simplify production.
You will notice a slight cut out on the slide rail of the receiver, This is where you flip up the forward part of the Bolt so you can remove the Bolt from the receiver.
Although there are some people who would argue otherwise, the best Enfields were the No.4 MkII made after WWII by Fazakerly.
Myself...I prefer a No.1 Mk V Trials Enfield (not to be confused with the Jungle Carbine - a No.5 Mk1). These were No.1 Mk III Rifles which had a flip up peep sight on the receiver with Ghost Ring.
Very Smooth Action.
