There is a chart of common German proof marks at:

Some discussion and a chart of the strange German gauge markings for rifle barrels at:

I doubt there is any way to tell exactly when it was made unless post 1912 with a date code. There is no way to tell how many old Rob made, we dropped a lot of bombs on gun factories at one time, you may recall.

It is, of course, worth precisely what your friend paid for it... to him.

As to ammunition, bear in mind that it has 65mm = 2 9/16" shot chambers, you will need to scrounge up some correct shells instead of the US standard 2 3/4"

Robert Hubner was a Master Gunmaker in Darmstadt, Germany - and is today a retailer:

Your Drilling has short 16ga chambers, as noted above - which, although will accept an UNFIRED 2-3/4" shell, are too short for the FIRED shell's length, as the longer shell's crimp will obstruct the passage of the shot charge ILO lying down in the chamber mouth, out of the way.

The rifle bbl is chambered for the 9.3x72R cartridge - "8.8" is the bore, and not the groove, diameter in millimeters.

It's intertesting, if not curious, to view a short-chambered, hammergun (ca. pre-WWI features) with proof, view & inspection marks that were not used until after 1950.

Hubner bought actions "in the white" from various makers, and completed the guns in his small shop.

IMO, excepting it's rounded action (The Sauer), your drilling looks like this blackpowder Sauer hammergun, down to the island back-action locks:

A few better, bright & clear pics of the marking & stampings on the barrel bottoms, and action insides (if any) might produce/ID a maker's mark.

The proof mark are standard for a WWI area German drilling gun. While the Suhl proof house went back to the SUW stamp set after WWII to not use the nazi stamps, they did not stamp rifle barrels with the diameter mark after WWII.
I used to love being able to hit hard at 1000 yards. As I get older I find hitting a mini ram at 200 yards with the 22 oddly more satisfying.
