What are the differences between the firing pins, extractors, and bolts of the No. 1 Mk. 3 and the No.4 Mk. 1?  Can you use a bolt tool on either or are different bolt tools made for each type?  Also, are the extractors interchangable?

What are the differences between the firing pins, extractors, and bolts of the No. 1 Mk. 3 and the No.4 Mk. 1?

They are dimensionally different between these two models.

Can you use a bolt tool on either or are different bolt tools made for each type?

The bolt tool is the same for the No1 and No4, it also works on the 2A.  To my knowledge it fits all the SMLE rifles.

Also, are the extractors interchangable?

Apparently they are different.  I just realized this, I thought they were the same.

Numrich lists two different part numbers between the No1 and the No4.  I use their website as a cross reference all of the time.
