Need Help Finding the Meaning of a Drawing Symbol

Looks like material specs. Maybe a sign for a material code. Check ANSI if they have this on their page. www.ansi.org

Can you provide more information and context for where this is used exactly.

What type of drawings and what was the reference above specifically referring to on the drawing?

That's the unobtanium concentration level symbol for the Mattel prototype Transformer action figure. Hasbro actually got the contract so this information is nothing but an interesting piece of toy history.

Isn't 4130 a clue?

I found it... I found it... It's a clothing specification.

There are Chromoly fibers running through their underwear to keep the seams from exploding!

Bachelorette #1, please.

Agreed. GA

Reminds me of the girl in the underground mars mutant colony bar in "Total Recall"

It might be 0.3 for nom carbon content....

I did wonder if it could be 'w', shorthand for the German werkstoff (material) but it wouldn't make sense to have 'mat'l' preceding it.

I have never seen this particular notation before, and I have worked with drawings from almost 100 years ago. As has been stated, we need more contextual information about these drawings. What country are they from? Are they from a particular company? This may be some company's internal material specification. For example, General Electric uses a corporate wide system, EMPIS, for material and finish specifications in all their drawings.

Aww that's no fun. It is so much more fun coming up with coming up with wild ass fantasies that match with minutia details not presented!

I will say that this looks more like ball point pen writing than pencil or fountain pen writing.

Maybe this is one of the metal formulas that metallurgist Walter P. patented.

Outside of this, let the fables begin.

Can you give us a bit more of a snapshot of the line of text? Is it possibly an early version of @ ?

Found in a character map program, Airal font.

Ȝ Latin Capital letter YOGH U+021C

ƺ Latin small letter Ezh with tail U+ 01BA

A clue?

It looks to me like a badly written "@" sign or "at"....

So it would read :- "material at 4130 specification" for me.

Looks like a letter or symbol from Arabic writing

In the day (just after WW II) when pierced and cast was the only selection, came along welded or wrought pipe, welded seam tubing and pipe. CP cast pipe, PT pierced seamless tubing and wrought pipe WP or welded pipe/tubing. For high pressure hydraulic and gas tubing, it was a while before adoption of WP in place of PT.
