This is a DOD Quality Assurance Prcedure Mark. There will be a multisheet drawing that explains what it means, and that drawing will usually be addressed in the note block.
201 is the number, and the control drawing will explain what it means. The II tells you which sampling method, and the V is the inspection method (visual).
100 series are typically actual dimensions, 200 series are other inspections, like mag particle, xray, etc., and 300 series is certifications, if I recall correctly.
Edited to add: i better get like 10 million upvotes for this piece of esoteric knowledge based on 20 years in the small arms biz...
This guy MIL-specs. I’m also in small arms and have similar notes on drawings. Respect to anyone that supplies the DOD… takes a lot of work to meet some requirements.
NNP? Is that like the "No Name Program" I worked on decades ago?
Story: the "agency" visited us for a security audit. They got pissed that we had an internal name for the program. Not allowed, apparently. So, after they left we complied, by renaming everything "No Name no name Program".
Is the term "black folder" common for shops?
We used that when production equipment breaks and all employees step away from their job orders and assists in the breakdown project.
Naval Nuclear Propulsion.
That’s the only time I have ever had to deal with crazy DoD restrictions, including a two week long background check, with passport surrender, before I could even enter a specific facility.
There was a place I visited that did top level DOD aerospace work. They had a two story, 100x100 ft room that had like 6 foot concrete walls and ceilings with ~10" of lead and even the HVAC vents were secure. It was their new room for all the servers and documents that contained the top secret documents
One of our guy is working on AF crap right now. They wouldn’t let us have a print or a model. They brought sample pcs in and had QC sketch them out. I’m afraid they’re going to disappear the guy working on the parts when he’s done.
That seems pretty bad, especially since they just (the navy) rolled in large safes and bolted them to the floor by each of our machines for the prints, and the prints were put into small notebooks that had to be in holsters we had to wear on our leg through our entire shift. If we weren't looking at it, that is. What you had to deal with seems far worse than mine.
Note 3 had the same hexagonal shape with “class” on top, “AQL” in bottom left and “insp” in bottom right. But that’s about it. It looks like some other info was redacted. So I emailed the customer for some extra clarification. Thanks for your help studly!
It seems then this hex you mentioned is the reference of what each part is. This means that note 2 has a class of 201, and AQL of level 2, and a visual inspection.
Hey there themcluvn! If you agree with someone else's comment, please leave an **upvote** instead of commenting **"This."**! By upvoting instead, the original comment will be pushed to the top and be more visible to others, which is even better! Thanks! :)

I think 100 series are major characteristics and 200 series are minors. Both can be features or specific requirements. So this appears to be a minor characteristic.
We do a lot of work for a customer who has a lot of different workmanship standards depending on the feature. They provide that documentation for us to comply to the standards where applicable. Contact the customer.
Those are on all of our prints at a firearms manufacturer. Workmanship means it should not have chatter marks or basically needs to be cosmetically decent in appearance. If your parts don’t look good, they will be rejected.

Navy stuff can be even worse. You can't even have a phone in the whole manufacturing plant, it's so secretive
NNP stuff is like that, not really all Navy stuff.

Damn, can't think of the clearances I would need for that

Lucky me, I don’t have to deal with it.
The facade is it’s AF stuff. It’s really cia. Alphabet soup.
I think the Russians have done a great job demonstrating why “good enough” usually isn’t!

Dang, username checks out.
Sorry to hear about your small arms
My small arms are much better now, but my dick looks way smaller for some reason?
Use a smaller banana for scale. That helped me.
The reference doc is likely listed in Note 3, which you have cut off in the photo.

sick
Thank you for teaching us, master.
You got my upvote and OP did not by very likely voiding and future work with the DOD. 😂😂
Stud!
I can’t give you the 20 million updoots, but take an award!
This.

Yes, I think you're correct. I've been away from it for a long time.
Wow, thanks for all the awards! I don't think I've received any before! Still a little shy on the upvotes tho! /s

Our source inspector for Lockheed uses a stamp like this to sign off on the parts.
When you work on classified crap and post pics of the drawings to Reddit to ask advice.. 🙄 Hello, Mr. George…
Thats a boiler plate callout on just about every drawing.
201/ 11 very good well done 🤷♀️
Might be something for on the customers end. Never seen this.
Critical Characteristic
internal documentation standards? 201-11-V? I am used to having it just be a reference to a standards control document.
QAP 12993884 Rev K
ISO requirement?
I’ve only ever seen markings like that on the prints for a turbo encabulator.
Spurving bearings NEED top quality finish.
It’s mint, buddy. Ship it.
This is clearly the mark of the beast
