Bolt Identification

[Rarecat 0]

I've found a couple of different bolt types in the various Johnsons I've acquired but I haven't seen detailed documentation on parts variations.  Here are two of the ones I've come across, can anyone ID them for me?  I think I know the answer but would like to hear from the more knowledgeable ....

The one without roller is probably a Dror bolt.

Yes the one on the left is a DROR bolt. My next question is ... Is it .303 or 8mm?

If .303 you will see an obvious size difference when looking at the bolt face. I had a .303 bolt in mine early on

and it took awhile to figure out why it kept dropping cases on extraction .

Once i figured that out then an easy fix by swapping to an 8mm.

Luckily it's an extra bolt, now I'm curious which one it is....

ETA: Crap, it's a .303

There seems to be more .303 than 8mm out there. Unfortunately bad place to start a build

I have been setting on mine for several years hoping that someone will pop up needing one.

If you ever come across someone needing more than 1 plz let me know.
