As promised, here are some photos of a reject(?) Kokura receiver and barrel mounted in a nice early stock. The barrel and receiver are in the white.

The barrel has a circled "ni" stamped on the underside. On most T-99 concentric circle rifles, this marking is usually present somewhere on the metal.

The receiver has a long crack beginning at the barrel junction and extending rearwards almost two inches.

Note the large metal spur that was never machined away from the right-hand side of the receiver forward the clip guide.

The stock adapts an early three-screw front band, however, the front screw hole is filled with a blob weld. A long rod is present which is retained in an early spring-loaded rod release.

The left-hand side of the receiver has no serial number, only the Kokura Arsenal symbol. A full, untouched mum is present on the receiver top.

The bolt is unserialized as well. The safety knob is a late-war, blob welded variant.

Everything about this rifle indicates a very late war assembly with reject parts. I'm most interested to hear everyone's thoughts about the circled "ni" on the barrel.

Chip, I have a similar example with just Kokura mark no series or serial number & barrel/receiver in the white. I've never taken it apart. My example never had front sight installed, doesn't have provision for cleaning rod. Need to take another look as I can't recall rear sight!?

That is one nice, ugly rifle. Thanks for the picts.


I would think you have it pegged, late assembly of previously rejected parts.

Only one question, on the crack, 2 inches? that would be through the receiver ring, looks more like 3/4", or is it just the picture?

Jareth,

This one has an early front sight welded crudely to the barrel. Also looks to have a retaining crosspin. The rear sight on mine is a non-anti-aircraft wings type.

If your curiosity ever gets to you, I'd love to hear if yours also has a circled "ni" on the barrel.

Don,

It's the photo. The crack tends to fade a lot as it extends rearward. At the terminus, it can barely be seen at all. The crack may have formed when the barrel was screwed into a badly manufactured receiver. The fact that the receiver was never machined properly or completely may be testimony to that.

Yes,
quite likely the assembly, or maybe it even cracked years later from the stress.

Great rifle, gee! I wish they could talk.

That is a very interesting rifle for sure, I can't say that I ever saw one exactly like it before. That is great and very find.

Chip, in photo number 2 there appears barrel separation in front of the receiver, or is that an illusion? Can you provide a photo of the same area (bbl interface with receiver) on opposite side?

Fred,

I'm sure it's an illusion, but will try to post a good photo later tonite to be sure.

Chip,
Have you an X-ray of the receiver?
I would be interested in the internal pattern of the crack.

Martin,

While I'm not certain, I think the x-ray department at our local hospital would probably take a dim view of me waltzing into their facilities with such a request.
Seriously, I never considered doing an x-ray analysis. How would one go about such a thing and how much would it cost?

Try taking in just the barred receiver.
Also, try the Vet's office.
I bet the reveiver was never correctly heat treated.

Chip, you might consider asking your dentist if his machine will handle that. You could put the bbld receiver in a fly rod tube or graphite rod tube to carry into a building. Just tell the curious you and your dentist are going fishing. Oh, well, the times we live in.
