No. 4 Mk 1 (T) bolt mismatch - how much does it hurt value?

[CINDERS]

As PL aludes to the kick in the nurries the easiest solutions to see if the bolt has been correctly fitted is to -
A) Get it to a gunsmith familiar with the lock up & contact points of the Lee Enfield get it checked if all good then you can work on the other stuff numbering & getting the bolt handle sorted if your gunna keep it if you onsell it one would expect you tell the new buyer its not the original bolt but is fitted correctly and was numbered to the gun.
B) If you have the experience & engineers blue coat recoil surfaces on the bolt and see how it is contacting as they are not just drop a bolt into an action and expect it to be safe.

Not QUITE that simple Cinders (see b) above but getting close. Full details of fitting a bolt AND setting it up so that all the interlocking features operate in unison are written down somewhere as I recall

Many years ago a kindly soul pointed me in the direction of a copy of the No4 EMERS. They've been an absolute godsend.

As my 4(T) has been through your hands, and the scope through Peter's, I wonder if some kindly soul out there would like me enough to do the same to me
