Need help with custom builder’s name

[stackbarrel]

I just picked up a classic custom rifle in a vintage caliber. Pre-68 Mauser action in a .219 Donaldson Wasp. Beautiful rifle. The only markings on the rifle are on the left side of the bbl .

.219 DON WASP 250 NK

I’m thinking 250th rifle built by “NK”? Anyone have any info? THX.

I'm thinking the chamber has a .250" neck diameter.

250 NK is definitely the dimension of the case neck.

Here is an example of what I’m understanding your barrel is marked similar too. If so then it definitely means neck dimension.

Definitely .250 neck diameter.

Thanks for the replies. It definitely was the neck diameter. My chamber cast confirmed that. Been making shells out of .30-30 brass and the rifle shoots great. Smoked a few chucks with it. It’s definitely a shooter.
