A quick question on Enfield bolt heads sizes

[brian30-378]

I have a bolt head and I am trying to identify, by the markings, if it is a number 0,1,2, or 3 head
I understand that they usually have the specific number stamped on the head.
This one doesn't seem to have a number.





Any help to identify this head number would be appreciated

No. 4 bolt heads are numbered. That is a SMLE (No. 1 Mk. III) bolt head. They aren't numbered. Selective assembly needed.

Only No 4 bolt heads have numbers. That's a No. 1 bolt head, and thy were hand fitted to each rifle.

Thanks for the responses. I had originally concluded that all had to have a number on the head.

The No 1 Mk III bolt heads were issued long and individually fitted. The trick is the find one longer than you need and carefully polish down the face on a flat, square surface.
