The 38 stamped on the hub shell indicates the year of manufacturing.

Looks like the OP has true "clincher" tires, not the "wired-on" type that we all call "clincher" now.

Yeah, I remember reading about those in Frank Berto's book. Never seen any in person, unless you count bicycle museums, though. It is nice that the Germans use a different word for these old tires. If you try searching on the internet for old-style "clinchers", you find nothing of pertinence.
Edit, did find the name. They are called beaded edge tyres in most English dialects.

Unfortunately, I think there's nothing to be had stateside due to the prevalence of the "single-tube" bike tires in the US market before they went to the regular wired-on design sometime in the '30s. You can read more about that here.

Just out of curiosity, are the beads on the original tires flexible? Or are they wire beads?
Edit, found out they are built-up with cord but have no wire.

Maybe the 630 (27") are the best way to go if they sorta fit and aren't blowing off the rim!

This was fun to search about. Looks like there are some on alibaba (cheap product and shipping!), but you have to buy a thousand. I'll keep looking for a cheaper-shipped overseas source. Or maybe Canada? Mexico?

These seem like the actual thing! Unfortunately, shipping is about 80 EUR It's a piece of history you've got there.
Scarlson and everyone, thank-you for spending your valuable time on this bike. The tires on the bike in the photo were 27x1 3.8" I shoehorned on for a while. They were much too short to have the front brake working, and they look lost being so much skinnier than the originals. Buying new tires of 1 1/2" for all that money to gain 1/8" does not seem worth it, unless they are measuring differently and the tires are much bigger than the 1 3/8" tires. Maybe the seller can email a photo of them on an NsU or similar bike. Also I am pretty much impoverished and have much more time than money. But I do not need to ride this bike, it has been hanging in the garage sans tires for a year now, and it is a bit too small for me anyway. I will keep an eye out for the right 1.7" tires, or maybe I will find some freakishly fat 27" tire laying around I can try on it, but I have never heard of any fatter than 1 3/8".

The factory is still there and producing Audi A4/5, A6/7 and the A8 line. Neckarsulm has an NSU museum as well: https://demomu.de/
