Based on the pedals, the Shimano components appear to be New 105, which would place it 1987-1989, if they are OEM.

Looks like possibly Czech or Polish language on the seat tube label. What country are you in, @oxygen?
Edit: Ah, Deutchland. Sehr gut.. Cool brake calipers; never seen ones quite like that before.

It's definitely not polish on the seat tube sticker. I'm almost sure it's German but correct me if I'm wrong.
Mannesmann was a German steel manufacturer who provided steel for Columbus and Oria for their tubes.
Does it say Walmart on the head tube?
EDIT: I just noticed it says "...mort"

Mannesmann is a big company that's into a lot of things- I knew of them when they made high speed, continuous feed dot matrix printers; they've gotten out of a lot of stuff too... I didn't know they did bikes.
That's a really cool bike- I hope it's your size and you can get it overhauled and lubricated and enjoy it!!!

My Quattro Assi is made with Oria tubing from Mannesmann. From what I can tell from the interwebs, Bill Lewis Imports wanted a private label Italian bike so they contracted with Tommasini to build the frames in Italy, but Tommasini would not build them with Columbus tubing because they did not want the bikes to compete with their own so Bill Lewis sourced tubing from Mannesmann. The bikes were shipping to Texas where Bill Lewis had them painted and decals applied. German tubing, Italian built, US painted and distributed. Cool...

A German private label brand would make sense. The black, red and gold banding on the top tube are the colours of the German flag while the lack of embossing for the apparent era is indicative of a relatively small and less prestigious brand. Of course, that would mean that it is almost certainly contract manufactured. The serial number may give a clue to the manufacturer and narrow down the dater range.

It's 7 speed, New 105, which would be 1989.

ITALIAN CYCLING JOURNAL: Oria Steel, Tubing for Frame Building
So, German steel, Italian tubing....
Oria RANF tubing was supposed to be similar to Columbus SLX and TSX tubing. I assume that this means that the butted main tubes may have been ribbed inside. Maybe the chainstays too.
Here's a chart showing Oria tubing dimensions. 25 CrMo 4 was the equivalent to 4130 Chrome Molybenum steel but Oria used other alloys probably equivalent to Columbus Nivachrome and so on.

Mannesmanm developed the process for seamless drawn over mandrel (DOM) pipe and tubing in 1888, a year before Reynolds.
They were famous for their thin wall bicycle tubing. German bike manufactures like Durkopp used Mannesmann tubing on their racing bikes.
We had a Durkopp track bike like the one pictured on display at our shop. It had been used in the 1936 Berlin Olympics and weighed ~17 Lbs. with steel components and wooden rims. I rode 1/2 a century on it one time. It was super comfortable with 71° degree angles and a 43" wheel base!
Mannesmann went in and out of the bicycle tubing business over the years. They supplied steel to Italian tubing supplier Oria after their last exit from the bike business.
25 CrMo 4 is the equivalent of 4130 alloy steel.
Judging from the Shimano 105 components plus what appears to be swagged seat stay tops, it looks like a mid level model that may have been contract built.
As someone else pointed out it's a time trial bike.

So is a mannesmann successful, understated, and rugged; whereas a ladiesmann smooth, charming, and handsome?

Oria was an Italian tubing manufacturer who used steel from the German steel producer Mannesmann . Mannesmann at one time had a tubing plant in Italy too.

I have Colombus SL and SLX frames in my stable but this bike is my go to bike... it really rides well and handles the punishment well - BUT it may be that my SL and SLX bikes are in very good condition so I am more timid on them? At any rate, the Oria RANF tubing is as light and very well built..
